Gum ache & sensation after sore throat.

One day before I had a minor sore throat or maybe a swell in the right part of my throat. Took medicine and it went. Soon after I could feel a sensation in the right part of my mouth. Though it was not major I ignored. From yesterday I found there is a constant pain in the back side of my right gums. No teeth ache no unusual situation just pain in the gums of only the back part. Sometimes bit sensation in the teeth also. Could eat drink everything just the pain in the gums and sometimes in the jaw as well. While touching I noticed there is a tonsil below that jaw which is by touching it hurts. So that tiny swollen tonsil and the gums which pains. How severe is the the condition? Is it something which is not much to worry about?
