Do i have tonsilitis?

I have a spots at the back of my throat and its very lumpy where my tonsils are but they aren't heaps swollen. I had a sore throat for a week its getting better know. just wondering if that is tonsilitis. I had the flu the week before and i have been sick almost all the time with colds for the last 6 weeks. but only got the really sore throat last week.Also feeling tired and exhausted all the time. But i am not feeling too sick any more apart from that.
