My hand is tingling right now and it did hurt. Now I'm really scared I wont meet deadline for my paper. Help?

Working on a paper. There are well described neuropathies that occur from working at a keyboard for long periods which occur due to nerve compression syndromes. I suggest you take a break, both for your hand and for your mental health! when you go back to working, pad your wrist and and elbow and stop every 15 minutes, even if it's only for a minute or 2.
