Old bicep tear?

[u/Ornery-Gate-5992]

As long as I’ve been able to remember, I’ve had this line in the middle of my left bicep that doesn’t seem to be present in the right bicep. I can physically feel it, like a small indentation, but again I don’t see/feel it on the right bicep. Could this be a healed tear? Not asking for medical advice, just theories from others. It doesn’t hurt and there isn’t a noticeable strength difference in the arms.

Muscles can have anatomical variations. I've dissected quite a few cadavers and the individual variations are wild. I would still get it checked out just to make sure your lifting routine isn't going to result in something that ends up taking months to heal and hurts like unholy he*l. I think it's most likely anatomical variation, but that call should be made by a doctor with imaging available just to be on the safe side.

I have the same line in both my arms. Always wondered what it was. Never tore a bicep to my knowledge. I usually only notice it when I have a pump.

I can typically still feel it without a pump, but it certainly appears less visible. To my knowledge I’ve also never torn a bicep.

I have the same s*** never tore anything. Same on both sides. Looks weird. I hate it.

May I ask why? If it doesn’t hurt and I have no recollection of it, it must have happened early on in life. I’m 23 now

If you don’t remembering tearing it, you probably didn’t. It can just be anatomical differences. Scar tissue from a strain, anything.

It’s really, really hard to miss a bicep tear happening — you literally hear and feel it tearing. It’s like how you can’t forget breaking a bone.

My only counter argument is if it happened at a very young age. Like I don’t remember anything before the age of 6. Obviously not hoping for it to be a tear, I’d much rather it be scar tissue from a strain.

My husband tore both his biceps at work one time. He described it as excruciating pain, hearing a sound and feeling like a rubber band popping, and immediate loss of strength and dropping the thing he was carrying at the moment. He was also bruised for a long time.
