I also have had foot problems since Covid vaccines. I am 67 years old with 0 medications. I believe that the vaccine has left us with a toxic overload that lands in the feet due to gravity. Since our lymphatic systems do not have a pump, we need to assist the flow of the lymph system. I have been using my Chi Swing machine for about a week now and the pain seems to be getting better. This is a natural way to assist the lymph systems. Do your research first to see if this is a good fit for you, I would NOT use this if I had any artificial joints. Good luck
