thanks vini,
no they didnt do any xrays or scans at all, just took my blood pressure(which was normal) and checked my reactions. The nurse said i was concussed but could probably ride my bike again the next day, which in retrospect seems pretty irresponsible. I called the doctor after having to go home from work last week and she said my symptoms were probably nothing to do with falling on my head!!! i was starting to feel that no-one is taking me seriously about this so its good to talk to people that understand. I think im gonna go and demand a scan tomorrow...
