On Friday I had some vaccines for Hep a + B as well as for Tetanus and cholera. I went to a party on Friday night and had my fair share of alcohol. On Saturday morning I was a little bit hung over and went to play football for 2 hours in blistering heat. Afterwards I had an intense headache for the rest of the day as well as abdominal pain and nausea. Today my headache is gone, but I'm still nauseas and my stomach feels funny. I'm tired and struggle to consentrate. what could be to cause of all this? I'm quite concerned about it, as it's not normal.
(I slept on a matress on the ground on Friday night and there was some guys fighting near my matress. Could I have sustained concussion due to someone falling over me or something and the football just aggrevated it?)
