Ideas for pain relief from Small Fiber Neuropathy (SFN)

I just wanted to pass along some ideas for those of you with idiopathic small fiber neuropathy. I am a 60-year-old female in excellent health other than the onset of this about a year ago. I do not have diabetes or any other detectable health issues.
I started some new things a few weeks ago and this week I have had some remarkable relief. I am not sure if what I have done is why, or which thing might have helped, but still wanted to pass this along just to give some of you some things to try.

I wear compression socks. This seems to help with the pain and pressure I feel in my feet and ankles.
I started taking Evening of Primrose oil twice a day.
I have cut my caffeine intake by at least two-thirds and now drink mostly green or black tea. I had heard that caffeine could irritate nerves...worth a shot.
I exercise, which I have been doing for over 20 years. I think it improves circulation which I think really helps with nerve health.
I added niacin. I will aid in blood flow, also good for circulation.
I use a cream called DMSO which i put on my feet and ankles in the morning (numbs the pain)

I don't know if any of this could be helpful for you or not, But I seem greatly improved recently......I have tried everything and am always looking for new things to try in order to function with this awful condition.
I am still taking 600mg of Gabapentin 3 times a day and 20 mg Citalopram once a day and have been for 9 months. I do not take any other medications.

Blessings to all of you and I hope there is a cure some day. I intend to keep looking for solutions that do not require medications!
