5 weeks ago I had a sinus infection which required 10 days of antibiotics. I improved only getting rid of the mucus in my nasal area, but still have a severe soar throat & neck glands with swelling, inner ear pain, extreme difficulty swallowing, on & off fever, and severe pain in my center chest when coughing, sneezing, bending, laying down, etc. My family Doctor told me to wait it out, but the pain is incredible. What should I do ?
