Dear Doctor, I have tingling in my palms and feet since April. Besides I also started having neck pain, followed by back and now knee pain. I was asked to undergo blood tests but everything was normal. I had vitamin deficiency in November and had same symptoms but this time it was not deficiency thing. MRI of the neck region was taken but even that did not help the doctors much as it showed a little findings which the doctor said is common with people who sit for long hours on computer. Also the physiotherapy here did not help. The process here is very slow. So I would like to travel to India and proceed with diagnosis. Who would be the most appropriate doctor (specialist) to address this issue and how should I approach the same?
