I have thyroid problem from 1 year. Almost 1 year back I got pain in my left leg knee and I was unable to sit on ground floor at the same time got pain in my left hand. I used medication 4-5 months but not reduced pain completely. Later on it reduced, but after words I used to get pain in my left hand again even now I am suffering from pain in my left hand. My heart beat is also increased in such a way that I can here it. My BP is varying from some times 130/90 to sometimes 140/100. please give suggestion to which specialist I can consult. And I have headache problem Which starts from my eyes. Once it comes it increases slowly. And I have to use medication compulsory to reduce it.
