In March last year I missed a step on the stairs and stepped out into thin air, falling very heavily on my front with my right arm taking the impact. My husband said it was OK - nothing was broken (he used to be a nurse).
So I soldiered on for a few months, finding it difficult to hangs clothes on the line, undo my bra and put my coat on. Eventually I saw my GP and had an x-ray and MRI scan - diagnosis: chipped bone and fluid on the joint. It seems that the description of "frozen shoulder" is a generic term that refers to any discomfort of immobility, whatever the cause.
I had a steroid injection (doctor said "I'll do my best not to hurt you" - which made me think it was going to be agony but it was just mildly uncomfortable). It didn't immediately make much difference but after a while seemed to have eased it a bit.
Went to the physiotherapist who prescribed several exercises (some of which I did - but not three times a day!). I found that manipulation by the physiotherapist helped much more. I then went back to an old exercise tape that I'd used several years ago (Rapid Results - Beverly Callard - "Liz" in Coronation Street). Just jumping around to music and keeping mobile seemed to help a lot.
Now, I can do up my bra, hang out the washing and get into my coat. My shoulder is still slightly uncomfortable but it doesn't stop movement.
I think the injection helped , and the manipulation, and the exercise. Hopefully kitttylester it will eventually get back to normal.
