No I have no other conditions, I have had blood tests for kidney, heart, thyroid, liver and anemia. These were all clear. I don't smoke and drink rarely.
Sorry I forgot to say I am not taking any other medication of any sort at the moment other than the Fexofenadine. Only taken the anti histamine tablets and the zantac as this was tought to be the issue with a high pollen count and possible reaction. Not of these seem to have any positive or negative effect. Except the Zantac which caused diarrhea and anal burning. Once stopped recovered in a couple of days.
