Posting for traffic, have namechanged too. I had a GP phone appointment (just returned from hospital, major surgery) as last week I discovered a thin, watery, grey vaginal discharge accompanied by the most dreadful smell. GP left a prescription at chemist. I have been taking antibiotics for 5 days, still no change. Of course I will take all the tablets but surely I should be better by now? Also feel crap. Why have I suddenly got this condition at 49yrs old? Could it be due to reaction to surgery, oncoming of menopause? Would value any help/advice to avoid this in the future.
