Facial Rash and complete body pain

Well, last night was horrible. My legs ached and felt like they were on fire. In my knees it throbbed and pounded with pain. I took the last muscle relaxer I had and some ibuprofen. I didnt know what else to do.

I woke up with my cheaks red and feel like a rash. Its hard to catch in a photo but on both the sides of my nose it's red and rash like. No actual raised bumps. Just red and irritated and feela inflamed.
