Almost a year back, one alcoholic night after a party ,i slept on floor in my friends apartment, the next morning I noticed a small irritation very near to my left wrist. After a week I found a small shikakai sized swell at that place, that wasn't having any sense. But now, after a year, that swell is in the same size but am sensing a little numb till my elbow. It's been a month the left hand is in the same numb feeling. I can do all the activities well with the hand, but a little numb feeling till elbow is still persisting. Can you please let me know why is that numb feeling, and what's that swell is due to. Are the both related to each other. What kind of medication is helpful. Please suggest. Thanks in advance.
