Did you ever get any responses to this? This morning my fingers started twitching on my left hand, almost as getting shocked. Now all afternoon my thumb has been twitching uncontrollably, comes and goes. It does it for about 5 or 10 seconds and then stops. But now my whole hand feels kinda funny and almost like I don't have as much control in it as my right hand. It's even slightly tricky to open a bottle of water. Anyway, I'm a 28 year old female, and I too am designer and use my left hand for shortcuts. I'm thinking it's probably from using the space bar, though. Have you looked into Carpal Tunnel? I wonder if this is probably a symptom. I feel like I have these weird little pulses in my hand, and there's no way I could wiggle the tip of my thumb as fast as it twitches. Very strange!

It could be Carpal Tunnel (CTS) as my friend (who is also a designer) had these same symptoms but she also had uncommon wrist/arm twitches as well.
Early Parkinson's or Amyotrophic Lateral Sclerosis (ALS) often start in hands and/or feet.

If you can, i'd get it checked out just to be safe. Sometimes these turn out to be nothing but a weird phase in your body, but with you both being designers it may be CTS.

It's uncontrollable, but painless, except you stop what you're doing to pay attention to it....the twitch demands attention! The left hand shoulder is a bit sore from the way I sleep. Maybe stress causes it. My feet have been tender also. I do have rational reasons for all the above, except for the twitching.. caffeine, perhaps? I hope it's not Parkinson's.

32 yr old male here in jax, fla. take a hint at what i do for a living - designer/design professor. recently got the twitch in left index finger and some times other muscles, mainly on left side. anyone been diagnosed yet?

My left index and thumb and right index have been 'twitching' for approx 2 weeks now and unsure what it is.

I was wondering whether its a case of RSI as also on computer and texting a lot of the day!

I have the docs on friday so hopfully can shed some light, but if anyone in the meantime has any insight please let us know

I have also been under quite a lot of stress recently and wonder if this has anything to do with it?

I just spent an enormous amount of time working with files on my computer, doing multiple clicks using my thumb over an extended amount of time. My thumb has been having muscular spasms ever since. No pain though! I play guitar, and cannot afford to have a twitchy thumb during a gig. This has to be related solely to the use of my thumb on the mouse, so I decided to change the mouse to my left hand, which will prove to be awkward for awhile, but I hope that giving my right thumb a rest will help. I also read to try Chinese massage balls for therapy, so I may give that a try. I typed this entire message with my left hand. Can't wait to see how my guitar playing is affected!

34 yr. old graphic designer - Type a lot with index fingers (hunt and peck) and command/control - V,C,X,Z with left hand. Started getting twitch along index finger, around to thumb, but only on left hand. I think it's from holding my left hand slightly up in the air, while my right hand gets to rest on the mouse. This minor action with lack of support must be causing enough strain that the tiny thumb muscles and ligaments are getting stressed.

Look where the control key is on your keyboard. It's finger gymnastics to hold it down with your thumb and cross all the way over it to get to the "V" key with the left index finger. They should shorten the space bar and put the command/control keys further to the right of the most commonly used shortcut keys. Who designed this thing? Okay I get the patent ©2009 studio3g.com

So I'm guessing the twitch on the left index finger is keyboard related and not merely coincidental. I'ts not painful but it gets annoying at times, especially when I'm trying to type..
I usually have up to 10 programs open at once and alt tab to swtich programs...I do it all day long prob. 500 times a day minimum..I tried switching to one of those ergonomical keyboards but can't get used to the dame thing.....
good luck twitching ya'll.

I am a 46 year old female and have had a right thumb twitch since I was about 16 years old. It is on and off but "on" quite a bit. I went through a period of about 3 or 4 years where it stopped and then it returned again. I will also get numbness in the tips of my fingers when I get really cold. Are the two related and what could it possibly be. If it were Parkinson's wouldn't it have progressed more by now since I have had it for so long. My paternal grandmother had Parkinson's and several of her family members have it also. I'm very concerned about this possibility.

I am a 28 year old female and I am NOT a designer I have been having this problem on and off for about a year . I don't spend a lot of time on the computer and in fact use my left hand only when two hands are required. I don't know if this makes sense but, I am so right handed that I can't hold a spoon with the left.I do play some instruments but, not very well . I have also started to feel the hum and then a twitch in my right hand also. Some time last summer was the worst, I had just mowed the yard and for at least an hour both hands continued to vibrate like I was still pushing the mower and it hurt. Not like a 10 on the scale but when it is both hands a 3 is pretty noticeable.
I don't know if we all have the same problem but, I just had to get it out somewhere because it is very upsetting. I have lost strength in both hands and it is a big deal only to me if you know what I mean. I have tried the magnesium supplements and it only cuts the tremors down but, I am at the highest I can take them without it having side effects.
I would like to know if anybody else feels an "electrical type hum" right before the twitching starts? It gets progressively worse each time until my left index is almost touching my wrist line and my thumb folds over it.If anybody knows what it could be it would be really appreciated

I just saw a doctor for my twitching right index finger because I couldn't sleep or concentrate worrying about what it was. I have had it now for a few days. He said not to worry about it. He said it is more common to have the twitch in the facial area, eye, lips, but it happens in the fingers too and should go away on it's own. It just happens and has to run it's course. However, if it gets worse or happens to more and more fingers, I should see the Dr. again. It is so annoying and the weirdest feeling, but not painful. Knowing that it isn't harmful really put my mind at ease.

Such a relief to know. Im a software programmer and nearly keep typing for about 8-10 hours a day with both my hands and all my 10 fingers. I've been experiencing this twitching of my left index finger and (occassionally) left thumb for a while now (and also had similar twitch below my eyes). A first glance at the Internet drew all kinds of fears in me (right from the vast number of neuro disorders to CTS and all those that seem to favor programmers).
I finally decided to ask my doc friend (fresh out of college) about it she said its ok and warned me not to spend too much time checking out the Internet for such issues and ask her if I had doubts.
Twitchy1000's reply re-confirmed and re-assured my thoughts and Im glad for it.

I am an extremely healthy, active 33 year old woman experiencing some fo the same symptoms you have all described. I do work with computers all day. But these spasms in my left hand began YESTERDAY at approximately 9:30am. First, I noticed some tingling between my pinky and ring finger then my thumb began twitching. The tingling is gone today, however my thumb and index finger are twitching about every 10-15 seconds now. I just realized the spasms got worse after i drank coffee, which i did both yesterday and today. If this does not cease by tomorrow, i will be going to see a dr. I do have a history of Parkinsons in my family and a good friend of mine (27 yr old male) was just diagnosed with ALS, by the top ALS specialist in the country Dr. Mitsumoto at Columbia University. So, I am pretty much scaring myself and just need reassurance. I will let everyone know how it went.

@Concerned_NYC:
I trust you will come out from the dr. with a big smile and wondering why you scared yourself, just like I did. Im still having them but chose to ignore them now. Ofcourse the assurance that adds to my optimism is that there is no history of a nervous disease in our family.
Happy working and happy visit to your doc, who I hope will tell you nothing is wrong. (I hate to think someone having these symptoms is on the verge of a major attack).

How did you get on at the docs conerned NYC?

Not only am I having the twitching in the middle finger but also it will kind of freeze and looks deformed and when it does the freezing part it does ache..I also get painful cramps in my forearm.. I work on a computer all day (customer service call center) and I will have to stop what ever I am doing when I get these and either wait for them to pass or try rubbing out the cramp in my arm.. There has got to be something someone can do about these.. looking over the postings people using computers is having an issue..
twitchy CSR

I am a 47 year old female in pretty good health. I take care of my self and don t abuse my body but.... lately my left thumb has been twitching allot!
I am an Artist and more importantly I work as a waitress and tend to load up plates on my left hand . To do this little trick I have to spread my hand as wide as it can go and balance the weight of 2 or more plates on my thumb ,pinkie and index finger.
I have done this about 40 to 80 times a shift for the last 9 years. Do you think this is the cause?
I am hoping it is because My Dad had Parkinson's at 55...(GULP!)He also was a healthy guy.
Anyone out there who had this from waiting tables?
Oh, my wrist hurts as well.
TWITCHY WOMAN

I am a healthy 45 year old male, about a week ago I noticed my left thumb was twitching a little, now a week later and I think It's doing it much more. I did get a new laptop that I have been working with my left hand. I doesn't hurt or anything, but even though I have no Parkinson's disease in my family, the thought still scares me.

My son is 10 and he just started twitching. It's his right index finger. He is on the computer all the time. I thought it was a bad thing and I always tell him to shut it off, however he can do some unbelievable things on a pc .. So I thought it was a good thing because he was learning a lot. Now I wonder if the finger twitching is because of his PC Activities. We brought him to a neurologist and they hooked him up to a brain scan for three hours. Everything came back normal and they said its just a tic.. I'm thinking its because he is always typing and when I watch him type his right index finger is always pointing up and he's typing with his middle finger... I;m going to do a test to see if I can get him to type with the finger that's twitching.. I'll get back to this room soon for the results
