I have had long Covid for over 3 years. It took forever to have it diagnosed. I had reconstructive foot surgery in November of 2021. I have had the pins and needles all over my body. My foot got worse to the point I was crawling through my house after the point the actual reconstruction had healed. I had nerve conduction studies that showed nothing. Yet, my right leg goes completely numb and I fall and my left foot and leg swell and turn red and blue. I was not diagnosed correctly until I had skin biopsies at the Long Covid Clinic I am now with. They show I have neuropathy. I also have chronic regional pain syndrome in my foot and leg, lower back and neck. This is the extreme version of neuropathy. I am now taking gabapentin(neurotin) to help with this. My pain management doctor says I will always have pain. I have light headedness and dizziness. I have been diagnosed with POTS. I wear an abdominal binder so I can sit and stand up without passing out. I have started therapy. Will see how that turns out. Please be sure to do some research about your symptoms on such sites as the Mayo Clinic, NIH or Johns Hopkins. You need to be a self advocate as much as possible. I had so many tests done over the years that showed nothing. I felt like I was crazy. Long covid is attacking my autonomic nervous system so every part of me is impacted. I also have gastroparesis which is miserable.

You are not alone. I had covid 3 months ago. I get tremors mostly in my legs but it goes up my body. I also feel weak and my appetite is gone. They did all kinds of blood tests and found nothing.
