Hi John, my sincere thanks for sharing that info. The link states that multisystem inflammatory syndrome affects children and adults who were previously infected with Covid. Thankfully I have not so I don't think that's what is going on. My symptoms also do not match which I was glad to see. I was recently told that the vaccine likely pushed me into an autoimmune overload which is not to say I have an autoimmune disease but rather there is now excess inflammation in my body and my immune system is unable to regulate due to the overload. As a result I am experiencing peripheral neuropathy and RA-like symptoms in my knees and hands. I am hoping that over time the medication I am taking, along with supplements and an anti-inflammatory diet will help. Many thanks again for your thoughtful reply.
