My 10 yr old daughter has a severe sore throat, no swelling of the tonsils, her strep test was negative, but I noticed small red bumps behind her right tonsil, almost looks like small blisters.  She has a low grade fever, not much drainage.  Not sure if it could be a cold or allergies.  I have given her antihistamines with a decongestant.  Thanks
Hi, Red bumps behind tonsils are mostly due to congestion caused by infection or allergy. Presence of fever indicates that there is infection. In my patients with these symptoms, I usually prescribe antibiotic like Azithromycin, Antihistamines with decongestant and antipyretic if there is fever. Dose should be adjusted as per the body weight of child. Do consider positive feedback as a credit to my work Let me know if you have any further questions.
