I think tinsy you have hit this spot on with regard to dealing with the GP.
I called the Hospital today as I had an open system with them for my wrist when I shattered it…. so I can go back anytime with no referal. they said as it was my whole side I could not go back to orthopeadics.. this seemed daft to me as it could be an old injury from that accident. So my only option is the GP again (4th time) if things were getting beter I would be happy but they are getting worse. I was asked by NHS direct if my GP had, taken blood pressure, pulse, temperature, done a reflex test, tested for diabetes, refered me for an x-ray or CT…. they have done none of these. The doctor at NHS direct was some what fuming that they had done no tests and just sent me away. In her words, neglegent. And oh joy my left arm is totally numb as I type. i just want to see someone who can find the problem, having 2 kids and this problem, I am worried… extra stress from difficult GP’s is not helping
