just wanted to add that I iced my feet 3x a day for a month. So I am wondering did I somehow damage the nerves in my feet which led to small fiber neuropathy?? And I have been prescribed so many medications! PM prescribed gabapentin 600 mg 4 x a day and nortriptyline 50 mg at night(he thinks it's CRPS) neurologist prescribed mexiletine 150 mg 2x a day and went to a psychiatrist because I was getting anxious/depressed with the CPRS dx and she prescribed nasal ketamine 3x a day, namenda 28 mg and low dose naltrexone 4.5 mg per day. SHe also said that she could treat my pain.
