I cut the side of my index finger with a super sharp razorblade on accident. it was so sharp that it was flexible. I didn't feel the cut right away, it was sore for the next few days, then i didn't feel it at all for a month later even though i would get random jolts of pain from extending my arm. Then the numbness went away and I actually did feel the pain as it got slightly better each month. I think i suffered nerve damage, the cut still hurts 10 months later even though I can't see it anymore. Will this pain ever go away?
