It looks very much like I damaged a vien, by tearing it slightly.

I was doing a type of concentration bicep curl. Pushing really frickin hard.

I noticed during my last rep the top of the bicep was flushed red and lit up like a red light bulb.

I backed off on the # but finished the workout.

Next day I woke up with a 1" round lump right in the middle of the vein on the face of my bicep.

I reduced it, and the swelling has gone down. Day 3 it is bruised around there and the vein is pretty sore to touch.

Bicep muscle is also pretty sore around there.

So I am going to lay off for at least 1 week. Probably check with the doc.

Anyone else ever heard of this or had this happen? Feedback?

Obviously I am pushing hard, so maybe I'll back off just a little in the future. This potentially is not a nice injury if it tore really bad.
