I have been suffering from post nasal drip arising which started as a bad sore throat since 28th June. I took some Dequadine tabs to help with the throat pain and then I went on antibiotics (AMOCLAV) to clear the phglem in my chest which had turned greenish. The discolouration phglem has subsequently disappeared but I am experiencing coughing arising from what I suspect remnants of the post nasal drip. I am now Betnasol N NASAL DROPS SINCE YESTERDAY. The Doc said it would help clear up any inflammation that may be causing the drip. I would appreciate any advice you can provide.
