I have this strange feeling in my foot that it iches, but when i scratch it doesn't help, like that ich is inside of my leg. what can that be?

Could be : Neuropathy, or you might just have skin fungus that you can't see.

If your doc: diagnosis is neuropathy, a supplement called Alpha Lipoic Acid at 12 K mgs daily may be helpful. Consult w/doc first. I see that you have OCD. If you do not have diabetes or a history of chemotherapy it's more likely a result of that. Peace and good health.
