I need some advice please. I've had a problem with my right shoulder/ arm since last June. It started with pain and pins and needles in my right arm and my hand sometimes becoming a bit purplish. I've had an MRI on my neck and brain and ruled out a prolapsed disc in my neck and MS. My GP eventually referred me to a rheumatologist and I had an x-ray in December and a CT without a contrast in January which ruled out any bone deformity. About 3 weeks ago something went clunk in my shoulder and since then I've been getting worsening blood supply problems to my arm. Sometimes the hand goes white and cold, sometimes really blue and sometimes dark red with popping veins. I've been back to my GP a couple of times and they have written to try and bring my consultant appointment forward. I've also been to A&E but they aren't that interested unless I can't find a position where the blood supply to my hand doesn't come back. As I live an hour away from the hospital this seems a bit scary. At the moment the symptoms are getting worse by the day and I'm getting a lot of pain at the front of my shoulder and under my armpit. I've been in constant pain since June. I don't really know what to do with myself and I'm losing all confidence in the NHS. What can I do?
