Apologies - a bit long and boring 
So I had a cold before Christmas which developed into sinusitis which I had a course of doxycycline (I think) for - beginning of Jan.
2 weeks later I developed an outer ear infection. I was given an antibiotic ear spray for that (can't remember what it was called.
After 4 days it was having no effect so I went back to the doctor and was given erythromycin (am allergic to penicillin) - as she felt I now had an inner infection.
Two days after that I got an outer ear infection in my other year but was told by the doctor to just keep the oral antibiotics going.
I managed 3 days of the antibiotics but then couldn't tolerate them any more (bad stomach pain and diahorrea). I phoned the doctor who gave me a course of ciprofloxacin instead.
I finished that yesterday. Today my ear is becoming increasingly painful again - I don't know if I have an infection again (haven't seen doc) but I suspect I have as my ear canal is very swollen again.
I just don't know what to do now. I've already had LOADS of antibiotics in the last couple of months but none of them seem to be touching the infection (other than to offer short term relief). I'm loathe to keep going and bothering my GP about it but my ear really hurts.
Anybody got any useful suggestions as to my next step?
