My son has been off chemo for about 1YEAR. He has developed neuropathy from one of the chemo medications (I can t remember the name). He has episodes to where he goes numb starting on his right side and travels to different part of the body one spot at a time. Tonight it started in his stomach, to his foot to his eye, nose, lips, teeth, butt , and he has a hard time spitting out words. It takes him awhile for the words to come out. His has tunnel vision. Why is this happening!? He is taking gabapentine. Now he can talk properly and now the numbness is traveling up his arm.
