Sharp pain in ear. But doctor says no ear infection?

Ever since i been swimming my ear been hurting so bad. I went to the doctor but they told me there was no infection but there was alot of ear wax in my ear. They removed it with a spray can or whatever doctor call it. And they re checked my ear and they said there no more ear wax. And sent me home with antibiotics as well since my brother had a strip throat. So its been about 2 days on the meds and i still feel the same. I can barley sleep without it hurting like a *****. I try taking to pain med Tylenol. But it still hurts. What my next step.
