Ok I'm new here my daughter told me to search for a group 4

Ok I'm new here my daughter told me to search for a group 4 foot pain. I've got so many questions and don't even know where to start. I've been dealing with major issues in both feet for over 4 years and is only getting worse. It all started after I got out of the hospital from covid. It started out just being sensitive to touch and just got worse I've gone to foot doctors. He's taking an x-ray. Couldn't find anything. Says it may...
