I'm in PT now for left shoulder pain. I developed severe pain in my left shoulder this summer when performing certain movements (mainly swinging a golf club). Lived with it until it got to the point where a full golf swing brought me literally to my knees in pain and range of motion was decreasing to the point where it affected basic daily functions. GP had no specific diagnosis, ordered xray which revealed nothing and referred me for PT. Been going 2x per week since end of October and doing exercises that I can at home in between.
While it is definitely better than it was before starting PT, progress has been inconsistent; some days it feels like it's improving and other days not. One problem I think is that the PT's can't decide on exactly what exercises I should be doing. Near as I can tell they seem to think that I may have a partial tear of the subscapularis along with minor rotator cuff tendonitis. We have discussed referral to an orthopedist for an MRI, but I gather that insurance will require full course (8 weeks) of PT first. If subscapularis tear is identified, more PT will probably be prescribed before surgery is considered. All the medical pros seem to have an aversion to surgery.
FWIW, my research on shoulder issues indicates that it is extremely difficult to correctly diagnose and successfully treat. Hopeful, but not optimistic that I'll be ready to go for golf by spring. Already preparing DW for prospect that mid February southern golf trip may need to be amended.
In February (2 months ago) out of the blue my left shoulder started to ache. This surprised me since I'm right handed and my right shoulder, although asymptomatic, makes funny noises (like a coffee grinder) and has some limited range of motion, and is the arm I threw with and held rackets in for many years.
I was in Florida, away from my doctor and PT office and did not wan to get into it down there, so I researched it online, and it got considerably better after about 5 weeks. After a few weeks back home it started up again. Just started PT this week, at the same office that saw me for an achilles rupture last Autumn.
Similar to others' experiences, diagnosis is difficult within the shoulder itself, as well as differentiating from possible pinched nerve from neck. I do have a lot of tingling down the arm when it gets going, but that is not necessarily definitive for neck issue, as the nerve down the arm passes through small space and can get pinched there as well.
Fortunately, swinging a golf club does not cause pain, although I wouldn't be surprised if it exacerbates the issue. I am a side sleeper due to back issues, and allergies. I do find myself on my back, snorting myself awake, or driving DW from our bed to the living room couch.
Sitting in a chair too long, or being on the computer (like this) can really irritate things. Basically I'm better when I'm active. When I'm tired and need to rest is when it really kicks in.
