I am on amoxicillin for sinusitis (it started on Thursday after a nasty virus and I saw the GP on Friday afternoon as it had become so painful).
I started the amoxicillin on Friday evening and have been taking them every 8 hrs since, so am 1/2 way through the course. I was also taking paracetamol every 6 hrs which made the pain bearable (can't take ibuprofen for medical reasons). By Sunday morning I was in so much pain in my cheek, head and upper jaw that I had to start taking co codamol rather than paracetamol.
The co codamol takes away the pain, but after 6 hours it's back until the next dose kicks in. I am feeling a bit better in myself today but there's absolutely no improvement in the pain: do I go back to the GP for different antibiotics or give it a bit longer (I don't want to bother them if it's not necessary but I've been really ill for a few weeks now and just want to get back to my normal self).
