Newly developed allergies, excema in ears

I got Covid/pneumonia in September of 2021. Since I have developed numerous allergies; tree nuts, several grasses, poison ivy, wine, blue cheese, laundry detergent, and severe allergic reaction to alcohol. I now also have excema in both ears, which is worse in the left, and develop rashes in random places, most recently my lower leg several hours after leaving a park (heavy wooded area, tall grasses feet off of a paved path), and a rash on my upper torso x2 weeks. Anyone know of anyone or heard of these developing symptoms?
