my neuropathy is not sharp, stabbing pain. it varies from tingling and numbness to aching pain and touch/temp sensitivity. it doesnt sound like you are experiencing what i do. try to stay positive, watch what you eat- low carbs, no desserts, if you think it may be caused by diabetes- but there are other symptoms of diabetes which are usually come before neuropathy, like peeing a lot and excessive thirst (how i first was alerted to my diabetes). you could also buy a blood glucose test kit at a walgreens or something if you really need to know...

i don't really know what could be causing your pain, is it in the muscles, like cramping?
