Chronic Inflammation in Jaw skin, tongue

I started having sore throat 3 months back which changed into a tonsillitis in my left tonsil, for the 1st time I had tonsillitis in my life, I did a 3 day azethromycin course and it turned effective, after a month again I got tonsillitis, this time on the right and it was much more painful, i had high fever, ear pain, headache. So I went to a doc, took an injection and a few anti-allergy tabs. It went to normal again, then after a month again my left tonsil got effected but i was just 1 inflammation spot so i did another azethromycin course and it went to normal. now since a a month i am having continuous inflammation in my inside cheek skin and tongue, one heals, another one happens, i tried some sore gel to ease the pain. they go away within a week or two but when 1 goes another comes couldn't understand the reason behind it. Right now I can see a few red spots on the surfce of my tongue which are ticklish and not that painful. Please help me out with the Cause and treatment. thnks!
