HI, I RECENTLY WOKE UP FROM SLEEPING WITH ONE OF MY FINGERS (MY LEFT RING FINGER) BURNING, IN FACT, I WAS CONVINCED I HAD BURNED IT COOKING EARLIER IN THE EVENING, BUT LOOKED AND REALIZED THAT WAS NOT THE CASE. AS TIME WENT ON THE PAIN WORSENED AND HAD SPREAD TO MY ENTIRE HAND. THERE IS NO VISIBLE DEFORMITY OR SWELLING SO I AM NOT SURE WHAT COULD BE THE CAUSE OF THIS ISSUE?
Hello, Welcome, and thanks for sharing your concern I went through your query, and I feel, such burning sensation could be a sign of nerve compression in the form of CTS, or median cubical or ulnar cubical syn Chat Doctor.  A proper evaluation from the neurologist will greatly enhance the chances of reaching to the correct diagnosis. I hope my advice would have been useful, in decision-making regarding your treatment, still if you have any clarifications or doubts feel free to contact back. Thanks.
