You have my total sympathy.
My shoulder is not broken but has been troubling me for over 6 months- variously diagnosed as frozen shoulder, osteoarthritis, bursitis, rotator cuff injury or tendinitis.
I have at times found it hard -sometimes impossible- to pull up my pants or jeans, reach behind me with loo paper (TMI!) hang up washing, do up my bra (even at the front, as twizzling it round has been hard) wear any weight of winter coat, reach the ticket machine at car parks, pull clothes over my head and cut my toenails! Knitting a cot blankie for my DD’s first baby has taken weeks but I am persevering.
On my own, there have been challenges but after two cortisone injections at least I am not in constant pain so how you are managing I cannot imagine!
