they hurt when i lift my arms above my head, and i cant tell if its my skin or tendons that hurt.
i have horrible stretchmarks on my lats and when i stretch my lats or do alot of pullups (which iv been doing a shitton of lately) my lats hurt real bad but its right where the stretchmarks are and they get redder
Yea kinda sounds like you have it too. I can't even think about pullups without my lateral bicep tendons throbbing. Luckily my arms are 32" and I don't need to work them much. I used to also play professional sports and was an army ranger.
