Nice to meet u Jacob.

I also have SFN dx'd with skin punch biopsy in Sept 2013. I have the same symptoms as u plus some fun extras.

My pain dr says the deep aching is not related to SFN but I don't believe that. Many on here have that type of aching. I also could not walk far or stand for any length of time or my feet started burning, stinging, electrical zaps etc. I also have the twitching u speak about.

Through trial and error I am currently on gabapentin 1800 mg a day, BuTrans pain patch 20 mcg/hr and 3 oxycodone 10-325 a day. This has allowed me to walk a little farther and stand a little longer. I have to be careful to not overdo or I'll be in bed for 2 days trying to recover. I do lay down frequently during the day which helps.

I'm a lady, 53 years old and I live in Georgia.

Hope some of my info helps u.

Take care and keep us posted...we care
