for some reason or another, my shoulder joint area of my right arm is fucked.

everytime i try to raise my arm outright and parallel to the ground, i feel a sharp, hollow pain in the shoulder joint area. its only when i do that action though. other actions such as swinging my arms while walking, etc are fine.

i have no idea how i got it, basically just woke up on Saturday morning and voila, 1x fucked up arm.

now im fucking pissed cos i cant do my daily pull-up routine.
