My heel pain started after the first shot of covid vaccine (Pfizer) but I didn’t think it was the vaccine. It was bad some days and then I didn’t notice it much. Attributed it to being on my feet a lot. Took the 2nd shot and then 3rd booster and my knees started to pain really bad after a long plane flight. I thought it was the long journey. But my friend a physical therapist told me to see my Dr. X Rays revealed moderate arthritis . Couldn’t believe it. I was not overweight, very active, never ate junk food, healthy vegetarian diet. Took NSAIDs pain meds prescribed. Physical therapy, the heel and now knee pain kept getting worse. first in one knee then both. Eventually within 2 yrs my arthritis was severe. The heel pain continued. I had to get a total (not partial) knee replacement surgery last year (3 yrs since the booster shot)! I am only 52. Too soon to get a total knee replacement. Now 1 yr after my left knee replacement I am considering right knee replacement. The pain in my heels has continued and now I have pain all the way up to my neck and scapula (shoulder blades). I have taken a 1) steroid shot in my heels - no improvement. 2) Orthotripsy in both heels (not covered by insurance) - audio shock waves in heels - mild to no improvement, 3) Stem cell shots in both feet. 30-40 % improvement so far but I have to wear 4) Custom molded insoles from the Running Store (Roadruner) / Walking Store. And use it in classic crocs. That is the only thing that helps with my heel pain. I have go wear them all the time. I used to be able to walk around barefoot before the covid vaccine. I did not make the connection before between the covid vaccine and my arthritis until another friend of my mind had the same effect after the booster shot and her arthritis was even more severe and in smaller joints too all over the body. Now I am starting to get elbow joint pain , neck pain (x ray shows mild arthritis but the pain is bad when pressed and stiff). I am doing regular physical therapy for every joint. Managing the pain with percussion massager very night and heat pad as well as Ayurvedic medicated oil. I also got tired of all the side effects from pain meds and switched to organic USDA certified Ayurvedic herbal medicine and they have helped me manage the pain. But I feel like I will have to live with this all my life. I am dreading getting my right knee replacement surgery done now. And now I also have really bad neck pain. The heel pain continues - lesser than before after the stem cell injections. But still cannot walk barefooted more than a few steps. I specially miss going to the temple as it it required to be barefoot. I read some NIH research on knee arthritis post the covid vaccines. I personally know of 4 people besides me who had the same effects after covid vaccine in the US.
