It's downhill from here, all the way
When one of the options listed is "shoulder replacement" you're not having a good day.
I don't generally like to write about bad stuff, and in the scheme of things, this isn't that bad - I'm not going to die ad I can do most things. As some of you who read this know, I've had an ongoing shoulder problem for some 6 or so months (maybe longer, I can't remember now). Anyway, it's pretty-much always painful, it catches, I can't rotate to squat properly etc etc ...
I've run the path through general GP's (NFI ...), misdiagnosis through GP's that should have done a referral straight away, to fixing a symptom; frozen shoulder, had two hydrodilations, that fixed the frozen shoulder, and lots of accompanying physio.
Finally last week we had an MRI done. Today I got the results. I have a labrum tear, a reasonable size one. May have been caused by any number of crashes, spills and other such rough and tumble stuff in the last year or so. They won't operate to fix it because it's in a shoulder that's got osteoarthritis. Ie: it doesn't get better and there's no point - rehab for the surgery is ~6 months and there's less than even odds that it would be any better. Other things listed include a bunch of placebos and "this might work" stuff and various painkilling drugs, and a shoulder replacement.
Basically I'm paying the price now for playing contact sports for 20 years. C'est la Vie. I'll be 40 this year. Wear and tear is catching up.
