been diagnosed with chronic sinusitis , been on allot of penicillin , had a MRI, which confirmed it. feels like toothache this all started after a root canal treatment. Doc took swab as i requested a year later & she found staphylococcus!! now ive been prescribed a combination antibiotic 500mg flucloxallin that i started today...I am taking a probiotic too. Ive had a minor athrostopy that almost killed me as the recovery was so bad, & i didnt take any time off work either, im good at the moment as im positive doing yoga & on leave for a wk im also drinking organic apple cider vinagar with water throughout the day.
