My uncle had the first dose of the vaccine about 8 months ago. I don't know if he took Phizer or Moderna. He never took the second dose because of the arm pain he experienced almost immediately after the first dose. He still barely uses that arm, because it's too painful to move or lift much with it. He takes care of about 10 horses, and his arm pain is making it almost impossible to lift and move around the hay bales they need for daily feeding.

I have heard lots of techniques mentioned to help end long covid, reduce covid symptoms, etc. Many utilize supplements like selenium, vitamin c, magnesium, vitamin d, etc. Are there any supplements or proven techniques that are working to help alleviate longer term physical muscle pain type symptoms caused by the vaccine itself?
