Waking up with headaches?

So I had mono last year and ever since then I've been going to the doctor every two monos because I would get strep throat. The doctor told me I should get my tonsils taken out in March but it didn't seem so bad so I never did it. I figured I'd grow out of this "sick phase" I've been in which I heard mono can do.
But for the past three weeks I've been waking up with headaches. Not ecrutiating pain, just like dull and makes me want to go back to sleep. Should I call the doctor about it? I've been missing class in the morning because of this.
