hiya, firstly, thank you for taking the time to help us! Since last Friday I haven't felt myself. Started feeling like a cold but woke up Saturday with a really bad headache, that bad that I went off my food from Friday afternoon and maybe a mixture of that and the pain, I vomited Saturday lunch time. I took some pain killers, two at 684mg each, as I am a frequent sufferer of headaches and usually it takes a lot to get rid of them. Since then, I have been really off food, not eating much at all, and again today I feel the nausia again, and I started to feel a headache coming on. I've taken a tablet but again I feel sick at the thought of food, feel quite weak and faint, have a bit of diarrhoea, and to be honest, I have had a headache every week for the last 3 weeks... they seem to be hurting more, lasting longer, up to 3 days, and having more side affects. I've never been sick with them until Saturday. I've been going backwards and forwards to doctors since I was 14 with headaches, and I'm now nearly 23 and getting not only fed up, but worried. I've never had any tests for it. Please can you help?
