I Am A Sinus Sufferer And Go To A Good

I am a sinus sufferer and go to a good physio who helps me in two or three sessions. This last sinus attack I had a bee sting which seemed to have aggravated the situation and now I have a bad rhinitis with masses of flegm more severe in morning with severe coughing till I retch.
Sorry due huge exchange rate this is not worth my while. Thank you for your help
