Very mild sore throat and white mark on tonsil

[cleverthing]

Hi. I do get sore throat from time to time like when I have a cold or from shouting or coughing ,but it normally ease of during the day and I never normally look at my throat when it is sore so don't no what it looks look when it is. Yesterday it started being sore but not to bad and I thought I had something lodge as it felt like it so I looked in mirror and noticed my tonsils are a little red not much and on the one side there a little white mark and only one, not to big you have to really look and go in very bright light to see it. I have been sneezing more then normal the last few days and my nose seem bit stuffy and I had a tickley cough the night before the sore throat started and still got a little cough but not really bad. I still got my appetite and still can eat and drink, doesn't effect that and I have no fever etc... I have looked online and gone from having general sore throat to tonsillitis , to oral trush and cancer which obviously panic me. I haven't been drinking much, so I increased my water intake and started taking Ibuprofen and Strepsils lozenges and garled salt water this morning . Can anyone help as I'm bit of a hypercondriac and always think that the things I see or read I have got. It's hard to get into my doctors.i got a picture but not sure how to attached it.
