I now have a new appointment, with the correct consultant on July 7th, and my GP has apologised and promised the referral will be done this time.
Pain wise it's as bad as ever. Mainly my piriformis, but that's because I can't sit on my coccyx, so I am left with sitting on my buttocks, so they take the strain. The acupuncture and deep tissue massage still don't seem to be doing anything, at least not noticeably. I'd like to say 'yet', but am loosing heart really. I see my physio again on Tuesday.
