I Started To Get A Cold By Noticing My Right

I started to get a cold by noticing my right ear ache. I thought it was my tonsils acting up again. But there was no change in the small size of my abcess. (I'm 18 so they won't remove my tonsils when it's never hurt when it's flared up.) My voice came and went as it pleased. And I would cough every few minutes of I wasn't active. I've been having this tickle cough for 2 weeks and now my stomach is hurting from coughing so much.
