Welcome, Hansong. Indeed, people with long haul COVID have reported neuropathy and other neurological side effects as a lingering side effect of COVID infection. Researchers continue to study these after effects and potential solutions. You may wish to follow the Mayo expert blog to learn about the latest research as it becomes available.

But first I want to connect you with other people dealing with small fiber neuropathy, like @chloeb2 @athenalee @ashleyy302 @kenc @davehayward1 @ubelinda @notgivingup17 @artscaping @erice10 @margie1234 @pacer3702 @retired123 @twobrooklyn @simina1234 and others who are looking for solutions, like you. That's why I moved your message to this existing discussion:

- What helps the symptoms of Small Fiber Neuropathy? https://connect.mayoclinic.org/discussion/tingling-from-small-fiber-neurapathy/

Hansong, are you in the care of a neurologist? Have you been to a post-COVID clinic?

Hello @hansong7, I would like to add my welcome to @colleenyoung and others. Fortunately for me I haven't had COVID yet but I do have small fiber peripheral neuropathy with only numbness and some minor tingling in the feet. Mine was diagnosed by a neurologist exam along with a few of the nerve conduction tests. I'm not sure anyone can answer your question of how far will it go. Each of us are different and in some cases if they can determine the cause and there is a good treatment they can normally provide relief for the symptoms. I don't believe there is any cure for neuropathy unless it's caused by a compressed or damaged nerve and it can be fixed with surgery - but that's just my non medical opinion from all the reading I have done.

One thing that has helped me is to learn as much as I can about my condition. There are two really good sites for learning about neuropathy.
-- Neuropathy Commons: https://neuropathycommons.org/neuropathy/neuropathy-overview
-- The Foundation for Peripheral Neuropathy: https://www.foundationforpn.org/treatments/

There is also another discussion where myself and others with neuropathy have shared our story and what has helped us -- Member Neuropathy Journey Stories: What's Yours?: https://connect.mayoclinic.org/comment/310341/

Did your doctor diagnose or think your neuropathy was caused by COVID, or have you been diagnosed by a neurologist?

Good afternoon @hansong7. Colleen, thanks for the introduction. You have had a year of symptoms that appear to be SFN, small fiber neuropathy. I don't know if my symptoms include such defined patches of burning and desensitized feeling. I did have the skin biopsy which came back with 0.09 % fulfillment which is severe enough to be somewhat frightening to me. At that point, I also was on gabapentin.

My suffering begins with and is related to the daily barometric pressure. The lower the pressure the more my body feels "pain heavy". About five years ago I begin experimenting with medical cannabis. Except for the gabapentin, I use different doses of medical cannabis including topicals for the tingles and tinctures for the heaviness and pain.

I am here for you to help with identifying medication and other types of treatment. MFR, myofascial release therapy is a must for me twice a week. That enables me to keep driving, participate in Yoga and practice mindfulness.

May you be free, safe, and protected from inner and outer harm.
