I was stung by a wasp about three weeks ago. Had a severe allergic reaction. Needed to epi pens and meds and was in the hospital for about 6 hours. That was three weeks ago. Since then, I do not feel good, I get almost daily fevers, chills, coughing, stuffy noise and a lot of mucus and really bad sweating at night. It has been about three weeks now and I am just tired of feeling sick. Any suggestions.
