Bilateral tendon subluxation? (front shoulder pain 5 years and ongoing

I am a 26-year-old male with five years of bilateral front shoulder pain. This has been an issue I just dealt with since I didn't have health insurance for a while but I really really want to fix it now. The only prior shoulder injury I’ve had was a left clavicle fracture at age 14, which healed without complications. condition hurts both sides of my shoulder at the same spots, which makes me doubt that old injury is related. It started randomly as I got back into basketball but I definitely did not injure it or overuse it then. I think it's possible during my couple years of inactivity, some anatomical changes occurred in my shoulder? As of now, I just deal with lots of pain and uncomfortableness. I am very healthy otherwise and am pretty active. But I fear that once I grow older, the pain will grow along with the recovery times.

A physical therapist tested my range of motion and I was very limited in some areas, while being slightly more flexible in others. A sports medicine physician and the PT diagnosed me with biceps tendinitis. Lots of youtube research I've done demonstrated quick fixes/exercises or remedies for biceps tendonitis but it doesn't help me exactly. For example, I saw a video on how to massage your biceps tendon and after doing so, my (front) shoulders hurt a lot for the next few days. The sharpest pain is in the front of the shoulder and worsens with pushing or overhead movements especially. When inflamed, the pain can extend to the side and back of the shoulder. I also experience soreness in both trapezius regions and feel a pretty stiff neck. I don't know if this is exactly related but it seems very possible.

I can manage daily activities and occasionally play basketball, but even moderate activity increases the pain to around a 4. I rest for days inbetween basketball so it doesn't hurt even more. I'd have to compensate certain movements to prevent the sharp pain I get from movements such as shooting a basketball. Attempting to lift weights can raise the pain to 7–8 (after cutting the workout very prematurely because of the pain already), so I pretty much never work out. The pain is like a pulsing pain. It'll hurt for 3-5 seconds and then relax for 3-5 seconds, and continue that pattern. It is more than enough to keep me up at night in pain if it is inflamed. If it's really bad, sleeping upright helps the pain.

Without health insurance this year, I did six weeks of physical therapy, but didn't continue because I didn't feel any difference. I had an xray show that I had a flatter-than-normal shoulder socket. The sports medicine physician said this could cause my shoulder ball joint to rub my cartilage more since the flat socket is not holding it in place. My physical therapist and another doctor mentioned that my biceps or shoulder tendons are loose and move out of place when I turn my arms in certain ways. This led my online research to self-diagnose myself with biceps tendon SUBLUXATION. I am getting an MRI in a couple weeks so hopefully I get more information then. The doctors so far have said I most-likely was born with these slightly abnormal shaped shoulders. I believe that consensus because the pain is the same location on both shoulders with no previous trauma. The doctors and physical therapists have not seen my exact condition with both my shoulders without previous trauma either.

Does anybody have any similar stories? or possible good news about (bilateral) biceps tendon subluxation? I want to fix my shoulders and finally be consistent in the gym for once in my life and play basketball without pain. Thank you for reading all of this
