Thankyou for responding.The initial reaction I had was 5 days after my iron infusion.The doctor did the one time infusion which is the higher dosage since my insurance was coming to an end.I believe it is normally broken down into a few sessions.I am just trying to figure our what happened.Maybe my body went into shock.I know that an iron infusion can lower your immune system too so maybe I picked up covid or another virus after the infusion which did more damage.The Doctors just can't figure it out.My slow talking,swallowing and chewing makes me think LEMS or Myasthenia Gravis.These can come on from stress,infection or a virus.An antibody for MG came back borderline,but the doctor said it is nothing.Some of these rare diseases don't even show in the bloodwork.It is frustrating.
