I take Alpha lipoic acid 600 mg daily. I retired from nursing and two days later I woke up with full onset of pinpricks from head to toe and in my eyes. I specifically asked my neurologist how many of his patients woke up with full onset of pinpricks. He said none. It’s rare. When Covid first started I got my first shot then 3 weeks later my second shot. January. First week in March is when I retired. Ask your Dr about Alpha Lipoic Acid. I only take 600mg and it really helped. I get occasional pinpricks. Do not double your dose (I read about that and it says not to take more than 600 mg. Always Talk to your Dr. first if you have pin pricks and see about it. I have small nerve fiber that’s idiopathic (no known cause). It does not run in the family. I believe the Covid shots caused it. I continue to take Covid shots. It did leave me with a burning pain that comes and goes in my left hand. Quite frequently. @rnlorena
