Could you be abit more specific? Like how often, what time(s) for how long etc do these "seizures" occur? Also do they go straight from arm to leg or is it that they are sometimes in one place & at other times in another? Do they happen after certain foods, exercises, rest etc????

Do you mean muscle spasms or seizures?

They move around from the arms, usually the right, to the legs. They last for different time periods and generally occur after extreme stress or mental fatigue.
No they are not muscle spasms.
My fiance had seizures several years ago and they completely went away. He just finished a 5 night 12-hour shift change at his job, that is he worked from 6pm to 6am 5 nights in a row with only about 4-5 hrs sleep each day, on top of that he was under extreme stress at the job. I don't believe foods are the problem, I try to keep us on a healthy diet. Any food culprits I should be aware of besides sugar?
Thanks for your help.

So they move from (generally) the right arm to the legs & generally after extreme stress or mental fatigue. For varying time periods.

Do they happen after/during sleep or rest or sitting in a chair or in a car or whatever & do they generally last say 5 minutes to 25 minutes??

You say seizures not muscle spasms, so could you describe the feelings you experience with them, as since we are in different countries I often find that what one nationality calls a spade another calls a shovel etc & in giving help/suggestions it would be best if we could try tio be talking about the same thing.

Have you tried rubbing any creams (for muscle aches) in to the affected areas (are the areas painful even if only some of the time?)? Have you considered position of limb might cause the problem by reducing blood circulation or hitting a nerve? What about hot or cold compresses, have these been tried.

Thank you for your reply. This information is regarding my fiance. The seizures occur while he is resting or asleep and are not painful. He sometimes knows when they are about to occur but other times not. You asked what a muscle spasm was, I understand the language difference. A muscle spasm is when a muscle goes into a hard contraction, I believe because the blood flow and oxygen is restricted, there are many things that cause this, fatigue of the muscle, injury, alcohol (drinks), etc. It is usually very painful and hard to ease. The seizures he is having usually occur at night and after lack of sleep and/or stress. I would say they last 10 to 25 minutes. Topical ointments are not the answer. He was on an anti-seizure medication in the past but could not tolerate the side affects. I just learned there is a new medication that can be taken at the onset of a seizure, dissolves in the mouth, and it is supposed to stop the seizure without side affects. My daughter is looking into that for me. That is new to me. Once again, thank you.
