On Thursday I Started With Chills And Severe Aching In

On Thursday I started with chills and severe aching in my right knee and bot side pelvic area. This continued on Friday now feeling like I had too much air in my lungs, if I breathed in much it'd make me cough. My temperature was 103.7 with a horrible pounding headache along with stiff neck pain. The knee and pelvic pain had lighten up. Sunday evening went to ER they couldn't say what it was, so said it was a virus. Monday headache is so severe and the right side of my face now is numb from cheekbone all around my eye is all swollen. Went back to ER they said it was Cellulitis. Gave me Amoxicillin and Cyclobenzapr. I'm not getting any better. What do you think? Thank you YYYY@YYYY
