ooh ooh, I'm here! I've never had a shout out for me before!
Sorry to hear about your mum but I can't be very encouraging. Mine is terrible and I'm resigned to just putting up with it now. I have seen the orthopaedic surgeon twice now and he has confirmed that it is at the worst end of the spectrum. I can't put clothes on, wash my hair, put my daughter in the car seat....Total nightmare.
He said the op can help 99 people out of 100 and I was tempted but I have a 15mo, had surgery last year (gall bladder) and the year before (c section) and I don't feel like making it three years in a row.
I asked about physio and stuff but he said in a severe case it doesn't really help. If it's less severe, physio is worth trying and if you are in N London, there's an osteo called Simeon Niel Asher who is quite expert in frozen shoulder but my surgeon chap said it would be a waste of money for me.
So at the moment I am experimenting with acupuncture (not making any obvious difference but maybe magic is happening to my Qi as we speak....)
Surgeon reckons it'll be at least a year before it starts to improve which is depressing but not as bad as the 30 months I read on the internet.
My chap is called Peter Reilly by the way - he works in Harley St and the Wellington Hospital if your mum is anywhwere near London and wants a specialist opinion. He is VERY nice.
