then a few days later I realise it's catarrh that's causing it. I cannot get rid of the catarrh. I have tried various medicines i.e Sudafet, Benilyn. My GP has just prescribed me Omeprazole Capsules as he thinks I have acid in the stomach. When I read the leaflet from the capsules, there is no mention of them treating catarrh. Should I take the capsules?
