I have been trying to get a diagnosis for unexplained pain for many years. Have seen a rheumatologist and am awaiting follow up. My blood tests results were negative for esr and c reactive protein but I have noticed that I am getting increasing pain in my blood vessels - arms legs and temples, Does anyone else with any type of vasculitis ever have negative blood test results for inflammatory markers? My gp wanted to treat my condition without going through the expense of investigating it due to the lack of these markers and I am worried that although I am now seeing a consultant I wont be any better off. My concern is that I am sleepwalking (painfully) into something more serious so I would be interested to hear of your situations.
