and I'm taking my medicine. ? I've had it for six or seven weeks and I've gone to the g p and she said to take antibiotics, so I have and it'll be my last day of taking them tomorrow. My original symptoms were blocked nose and pain around my sinuses but now it's both of them and earache, headaches, tiredness. The antibiotics are called erythromycin, these put yu off food don't they? Cus I'm not hungry anymore? And they've given me diarrhoea? Is this normal? Yeah so what should I do, the antibiotics haven't worked I don't think? And I can't have penicillin I'm allergic.
