I am on prednisolone 30 mg every other day and Azathioprine 50 mg Morning and 100 mg evening to manage polymyositis. I am suffering from cavity and pain in my first molar right lower jaw since 15 for fifteen days and radiate to my right ear and feeling constant pain inside my ear. I took paracetamol 500 mg and then acetofenac 100 mg for pain at night and 100 mg acetofenac in the morning to get relief. I noticed some blood inside of my ear at night which I cleaned with cotton buds and there is no more blood noticed after that but I felt great after that. Now I want to know if I can take some antibiotics to fight this infection if yes, then what antibiotic should I take, what should be the appropriate dose, what should be the frequency and duration of the treatment along with painkillers.
