Thank you so much, @johnbishop
I'll read up on all the links this week.
My symptoms (I like lists):
I get pins & needles mainly in my feet and occasionally my hands. These episodes typically last days then go away. I usually wake up with them. It appears that walking and exercise help. Sitting and laying seem to contribute to the issues but I'm not sure.
I occasionally get sensitive patches on my forearms. I have developed two numb spots on my left foot. Right at the back of the heel and on the top of the foot. I sometimes get sharp stabbing pains in my toes and very occasionally my fingers. Sometimes I'll get a stabbing pain in my toe and somewhere else higher up on my leg at the same time. Completely synchronous.
My nerves can become hypersensitive. For instance, sitting I can start to get pins and needles within a minute but it goes away fast if I stand. This seems to be worse if I've been drinking lately. I stopped completely a week ago and before that I had cut down to just a couple of drinks a week. Beer seemed to affect me those most. Occasionally if I hold my phone too much the next morning I'll wake up with pins and needles in the spots where I held my phone. Also, occasionally, I wake up with ulner nerve inflammation symptoms. Usually on my left. I bought a thicker pillow which seems to help. It again seems like drinking alcohol makes me more susceptible to it.
Lastly, I feel like I may have had some of the autonomic symptoms with sweating and light headedness but it could just as easily been anxiety given all the news I've been absorbing.
I've had nerve conduction tests, poking, reflex and various blood tests. I pass all the major nerve tests as many of us do with SFN. I need to follow up to understand some of the more recent blood tests but I think we've ruled out some rare conditions and Cecelia. My fasting blood glucose has been hovering at 100 for many years. My cholesterol has been around 280 with triglycerides at or higher than that. Quiting alcohol and eating better has dramatically lowered them. I believe my total cholesterol is around 200 now and my triglycerides are 168.
I'm vary curious about the affects CBD (topical and other), marijuana in general, and Sildenafil (generic Viagra) might have. I've read some studies on Sildenafil with rats. My neurologist seems open to a skin biopsy which I just requested. I'm hoping to get an official diagnosis followed by genetic testing. I read that a mutation in SCN9A is something to look for and could influence the type of treatment. I have all my DNA sequenced but I don't know how to read the raw data correctly.
