A few weeks ago I posted about my shoulder pain. Somebody - but not sure who, SORRY, asked me to report back after I'd been seen and got diagnosed.
Today I saw the physio and he reckons I have adhesive capsulitis aka a frozen shoulder. Duh, so not a rotator cuff injury as I'd suspected. Fortunately, I've been doing the right things meantime - using it carefully but not immobilising, using heat, etc. I am a bit perturbed as my mum had a frozen shoulder and her Parkinson's was misdiagnosed as this to begin with - but of course just a coincidence as mum was also early 50s then and PD is notoriously hard to dx. And frozen shoulder can run in families.
It seems I am a textbook case for frozen shoulder as in female, 50ish (so perimenopausal), and have various autoimmune diseases. Pissed off but somewhat relieved to now know what i am playing with, and off now to do my exercises.
Pretty good service there - only 4 weeks frm my self=referral to being seen by physio. Good old NHS Scotland
