Ok about a month ago I noticed something super strange whne I was just touching my right arm at some point. On my right arm, I can feel a tendon or something and it sticks out quite prominently all the way from where my pec inserts into my shoulder down to my elbow almost. On my left arm it's all covered by muscle or something and can't feel it at all.

Has anyone ever heard of something like this? It's weird because it doesn't really cause me and pain or anything like that, i wouldn't know anything was different if I hadn't felt it. The whole tendon just seems popped out. I'm in a situatino where I can't see any kind of sport medicine doctor for a while so I'm just sitting here feeling pretty concerned hoping I haven't done some horrible damage to my arm. thanks.
