I am 50 year old male and I am facing severe pain in my left hand middle figure nail bed for the last many years increasing day by day. The pain extends upward over the whole arm right till the center of my chest. My heart check up such as ECG, TMT, X-ray etc. All have been normal. The pain increases the day I uses my computer more. If I get hurt even little on that figure location, the pain becomes unbearable. Colour dopler test & X-ray have also not shown any abnormality. Except that visually the colour of the nail is different from the other hand and little curved.
