Hi…as a point of clarification…the EMG test you had will only find evidence of large fiber neuropathy. As some mentioned, it takes biopsies to detect small fiber neuropathy. This small fiber neuropathy may be what is causing your foot pain. It sounds like you have good medical care and plan to talk of possibly having the biopsy. Best wishes to you.

Hi, Bjk3
I have the same problem. I had blood test, sonogram and am EMG. I had an MRI before all of this. It showed bulging disc, a herniated disc and a collapsed L-5 to S-1. I went to 2 spine surgeons. Both said they didn't see pinched nerve and didn't offer to do anything to fix my back.
I'm in Tricare for life. I guess they didn't think they would get enough money. Your problem is probably in your back. My feet swell. Especially on the bottom and my toes swell. when I get up in the morning the swelling is gone except my toes. It gets really bad when I'm driving.
I've given up on doctors. Most of them are idiots. My Neurologist us a good man. He did all he could to find out what was wrong.
Hanf in there,

@nemo1 I’m looking at this from a different viewpoint because I have experienced and had surgery for pain caused by a spine condition. Your reports indicate radiculopathy which is compression of nerves as they leave the spinal cord. This type of issue is treated by decompression surgery to free up the bone growth or ruptured discs that cause pressure. Once a disc herniates, it causes inflammation and overgrowth of bone, essentially arthritis in the spine. This often does cause sharp burning or electric pain when nerves are compressed. The report also mentioned compressed nerves in the cubital tunnel which is in the elbow. That can add more pain, and it is possible to have more than one compression area on the same nerve. Have you had an opinion from a spine surgeon about your pain?
