My question is in regards to my right Tonsil. I had cleared up my cold symptoms a week ago today (Last Tuesday).The sypmtoms were just stuffy nose, and a very light cough. A few days pass and (Friday) my right tonsil becomes sore. I dealt with it Friday, Saturday, & Sunday I couldn t take the pain so I went to the ER. I had a strep test that came back negative. The doctor thinks the cold just trickled down & is stuck there. My right tonsil is bright red, lymph nodes are swollen, & my neck as well ( a little stiff). He perscribes me Mucinex, Tylenol, and lozengens. Almost 36 hours into treatment & there is no change. My neck is a little stiffer, but the Tylenol is not helping with the pain. Should I go back to the ER?
