My daughter is 18 and never gets sick. She is very active. Last Friday she woke up not feeling very well but still went running. She went to work and said it felt like she was walking through quick sand. Every muscle hurt. She came home and has had fever, chills. We went to Insta Care and they tested her for strep. It was negative so they sent us on our way. It has been 5 days now and she is no better. She has no appetite, a headache, and says she has a pain in her stomach area. Her tonsils and lymphnodes are swollen in her neck. Not sure what is going on.
