Covid infection and shots that cause your body to make the toxic spike protein affects the nervous system and nerves plus damage endothelial cells. It sounds like you have small fiber neuropathy and/or blood vessel spasms. You may want to have your neurologist do a small fiber neuropathy skin punch biopsy. You may also want to see a vascular/vein specialist.

My teen son has Raynauds syndrome on his arms/hands and legs/feet and had Covid 2 times and gets red/purple skin changes/mottling. I have small fiber neuropathy and had 2 Covid shots and the Covid infection once.

Does your calves and ankles hurt/burn/feel warm? A neurologist can prescribe gabapentin or Lyrica for nerve pain and taking alpha Lipoic acid, Acetyl l carnitine and magnesium has helped me.
My son takes magnesium and omega 3 to help him with his symptoms (also helps his migraines).
