I have heavy legs and heavy upper arms and numbness in my groin area.I also have loss of feeling in the trunk of my body.I can't believe I can walk at all because of how weak I am.I had the Pfizer vaccine,but just the first two doses and no additional vaccines or boosters.I think all of these symptoms are brought on by covid,but I am sure the vaccines are not the Best either.Who knows what the side effects of those will be.When I went to the Specialist he found a Borderline antibody for Myasthenia Gravis.There are different types of Myasthenia Gravis and there are different types of Myasthenia diseases.You might want to get checked for it.They can be brought on by covid,infection or extreme stress.I was doing research and long covid clinics are using mestinon to treat long covid patients.Mestinon is the same drug used to treat Myasthenia Gravis. It helps the muscles and nerve signals to work properly.They also have been using it to treat Chrnoc Fatigue.I think Chronic Fatigue,Autoimmune diseases and Epstein Barr are all being set off in the body from Covid.
