Ringing Right Ear. Tenderness Under Right Eye. Sore Tonsils. Symptoms
It can be sinusitis.
Detailed Answer:
Hello dear, welcome to Ask a doctor's service.
I read your query and here is my advice.
I don't think that this can be tonsillitis because you don't have fever.
I think most probably it can be a sinusitis because you are having tenderness on right eye and ringing right ear.
You are having sinusitis reoccurrence since you are saying that you had history of sinusitis in past.
It has been for quite long, 8weeks so antibiotics are necessary.
If you were my patient I would have treated it with augmentin and decongestants.
You should visit your doctor for a prescription because I don't think you can take them in pharmacy with my recommendation.
Hope I have answered the question.
Let me know if I can assist you further.
