I have a serbacious cyst on mu back that is infected, I saw a doctor on the weekend who has prescribed penicylian to address the infection before he could remove the cyst. Yesterday it came to a head like a big pimple and started seeping, I wiped off the discharge and cleaned it, Then placed a sterile dressing with anticeptic ointment over the area. This morning we changed the dressing, cleaned with disinfectant, and again placed a sterile dressing with anticeptic over it. I spoke to the doctor, he said that I should continue on the penicillin and there is nothing he can do until the infection has been addressed. It is modratly painful with the pain increasing as pressure is applied, when I lean back etc. I can't sleep on my back due to the pain.

Is there anything I can do?
