I can imagine shoulder dislocation

chit; my right hip will 'lock up' on occasion, and I'll have to continue the motion I was making so it pops right again. Damn steel rods. Chiropractor loves me to pieces though
Arthritis, thank God that's one thing I don't have...I may get RA though, but with my aches and pains, I'd hardly notice a difference.
Nice to see your issues can be taken care of

good luck.
And as for getting old, I just read recently that not only do those of us with cerebral palsy age prematurely because we put forth 3 - 5x the physical effort, etc. than anyone without a handicap , but our depression rate is 3 - 4x higher; not because of the disease's severity, it's based on how well a person copes.
Coping with any problem in a positive light, and staying optimistic has scientifically shown itself to aid the healing process of an injury - almost 100 percent sure on quoting that one verbatim.
So keep smiling, and shop online while you recover. Good luck.
