I have idiopathic small fiber peripheral neuropathy in my feet. The methadone takes care of all the pain: burning, stabbing, pins and needles, shooting pain, extreme sensitivity. Sometimes it feels like someone has a nail and they are trying to run it through a spot on my foot. It is a different spot each time. Sometimes I just have to laugh when that happens cause nothing is touching my foot. The numbness is always in my feet but it doesn't bother me.
