Yesterday I took a overdose of paracetamol x10. I was taken to hospital to have blood tests, where they came back clear. However, the next day I felt really ill. I had a sniffly nose, sore throat and my ears hurt. I could also taste blood in my mouth. Later on in the evening, which is now, I started getting stabbing pains in my stomach and my back. Is this a delayed reaction of the overdose or nothing to do with it? What should I do?
