I was diagnosed with PANDAS syndrome I often run low grade fevers, have fatigue, and chills?

I am 18 years old, female, 5’1, 106lbs. I was diagnosed with PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated With Streptococcal Infections) in 2012. I keep getting strep, I had it at the end of November and I was diagnosed with it again at the end of January. I know I’m not reinfecting myself because I changed my tooth brush, sheets, and washed all my clothes. It took me over a week for my fever to break and I have bad mild chest pressure. I keep getting tonsil stones the size of peas. When I don’t have strep I often run low grade fevers, have fatigue, and chills. I do have a history of throat problems. Please advise?
