I noticed the other day after a good arm workout that when I did a front double bicep that I was not able to contract my left arm very well. Then saw as I did contract it the bottom of my arm (triceps) right into my armpit would indent and not be very full. As in the picture below I came to notice a lump.
There has been little to no bruising, triceps feels weak when trying to contract, and if I try to push my self up it hurts from mid/under arm to the origin.
Any suggestions? I don't think it is a full tear, hoping just need some time to recover.
