I also have profuse sweating. On and off all day long with or without any exertion. Hot flashes are somewhat controlled with an SSR, but nothing so far has helped the sweating. This has been going on for 15 months. Most of my other Long Covid symptoms have gone, but this still lingers. Now my lower face has become swollen on both sides. CT and MRI say they are fatty buccals. What caused this and what is the cure?? So far no doctor knows. Even the Mayo Clinic told me that they do not diagnose, so no help there at this time. No doctor has even been interested enough to look into this, so I am trying to find cause and cure. I would be interested to know if the vaccine helps you. Please keep us informed. Thanks and good luck.
