I'm 17 and I've had a fever ranging between 97.7 to 100 for a year now. My doctor said it's pleurisy from TB and I've been on TB meds like Akurit4 and Rcinex. The pleurisy fluid's gone and I've gained weight, but the fever hasn't stopped. Now my neck is swollen on the left side for the past 20 days. What could be going on?
