This is kind of an embarrassing question, but I''m a 20 year old male. About a week ago I noticed some pain in my pectoral muscle and when I went to go touch it I noticed this long lump in the left side of my chest. It starts about slightly to the left of my sternum right where the muscles starts and seems to continue horizontally across about half my left pectoral area. It''s rather raised towards the middle of my chest but slowly becomes less pronounced as you move to the left until it finally disappears. I''m not really sure if "lump" is the best way to describe it considering it feels more like a a very think tendon, almost like a tube, or something along those lines but it isn''t really movable. It doesn''t hurt anymore, even when I put pressure on it but doesn''t appear to have gone down in size. I recently had some blood work done which came back completely normal except for a liver enzyme was slightly abnormal. Is this something I should be really worried about or could it just be a strained muscle or something along those lines? Thank you.

Edit: Figured I should add that it is in no way near the nipple. It starts about two or three inches below the collar bone and then extends horizontally across the pectoral from there.

Without examining you, I really cannot offer you a specific diagnosis, unfortunately. It could be a lipoma (a benign overgrowth of fatty tissue), or it could indeed be due to a recent muscle strain (did you injure this area recently).

I see nothing for you to be embarrassed about in this case, and so I would recommend that you ask your doctor to have a look at this area of concern.

important
i have the same exact situation to the t. i am worried because this "tube"like lump thing that definitely stands out from my right peck feels like it doesnt belong there. i work out daily sometimes not enough rest in between chest days,maybe this doesn't help.i dont have coverage right now can any one explain what this is? im sure if another person has identical symptoms there has to be a very probable chance that this is a well known or maybe even common issue,thanks

all you guys should google: Trigger Points.. they are knots in muscles and they should be treated. They happen to form cause of wrong form,while walking working and doing other stuff. I have one on my left pectoralis major muscle,far from the nipple, close to the shoulde. I have noticed it yesterday before I go to bed, when you touch there there is pain. It is hard and like thickened rope on the fiber.I scared the s..t. But it is not a soft lump it is not a growth or anything. I am workimg out hard and with poor form and heavy weigts so thats a clue to follow and I have diagnosed the lump by touching feeling etc that it is a muscle trigger point.. Then masaaged painfully and deeply with my fingers to soften it, about ten minuteshuge pain and it radiated, also I have found similiar hard tissue knots on outer sides of my pectoralis major muscle. I went to bed when it is too much pain to bear to keep massaging, slept, and now I have woken, the pain is lighter and in a larger area.. But the lump is not that big anymore.. Muscle is more relieved.. I now know that these nasty trigger points are already formed on my kneck muscles, trapezious muscle and back muscles.. I only happen to learn about them yesterday when one became too big and became painfull. I will now try to eliminate all of them from my skeletal muscles. I advice you to go tell your doc about trigger points and ask for the treatment if he agrees the diagnose.

Bump on 4th Rib/ Tight Pectoral
I have the same problem. I only noticed it last week. I have lost a lot of weight over the last year, and have never been this skinny before (or can't remember when last I was in such great shape), so I don't know how my chest is supposed to feel. It being a tight muscle with trigger points is a very probable. As I am studying massage therapy, I know all about trigger points and how to treat them. You can try to treat them yourself, but you'd have to know where to look for them, and how to treat them, as the whole muscle might not be affected (the Pectoralis Major has 3 sections). With that being said, I think just to be on the safe side, I will go and have x-rays taken and clarify whether or not it is only the muscle.

Im finally diagnosed and symptoms are worst as its been 2 years. I have Thoracic Outlet Syndrome. Very hard to diagnose. Some docs dont believe it, if you think you might have it, go fight for it. There are specialist like Dr. Dean Donahue at MGH in Boston, Dr. Pearl in TX, Dr. Thompson and St. Louis Missouri etc. Those are just the ones I always hear about. You could also go to the Barnes J Hospital. Thanks. Hope I can somehow help someone. Theres also a group on Facebook. my symptoms now besides the lump (its hypersensitive btw. pain in neck, upper back, between scapula, collarbone area, under armpit and down my arms to my hand. dull achey pain etc.
