I have had a severe sore throat, swelling, red, white spots off and on. Lymph nodes swollen for about 5 weeks. The first week I had a strep test which came back negative. Last week I went back to dr. and he said maybe allergies? Claritin D. a week later still taking Claritin D, no improvement and pain is so bad I have to take motrin every 6 hours. Hurts to swallow. Exhausted all the time.
