The Pain Goes On

I sat in the office today trying to work but in continual agony. And now I am suffering a reaction from the antibiotics - a very itchy skin rash. I am taking the painkillers and have bought oil of cloves, but to no avail. The only thing that helps is neat whisky, swilled round my mouth. And I have to spit it out because whisky is not recommended with painkillers and antibiotics. I am worried about my trip to Scotland on Saturday - will be pain be unbearable during the flight in the low pressure?
