Sharp pain in the back of the shoulder!!!
I don't exactly know what it is that is hurting but it's like this round thingy when I flex my shoulders backwards (kinda like the one highlighted in the picture but unsure). There is a sharp pain in that area while doing random things like push ups or sudden jerk movements or lifting heavy stuff.
For context, my right shoulder is kinda messed up. 2-3 yrs back, I used to do these HIIT workouts where I did a shit ton of push ups with very bad form and no back exercises whatsoever. Over time, this started hurting my shoulders. Initially, it used to be an impingement on the front shoulder. Then eventually, while doing those shitty push ups, the pain shifted to the back of the shoulder (dont exactly know where). I feel like negligence of back along with spamming push ups started it but I cannot really tell.
If anybody has had a similar experience or knows about this, pls help me out.
