Hi, so a month ago now I was in a wake boarding accident and I went face first into the water at a high speed. I was diagnosed with concussion, I had a very painful headache predominantly located on my front left side of my head as well as dizziness, nausea, fatigue and sensitivity to noise and light. For the first two weeks I couldn t bare to be out of a dark room especially without a bucket as I could literally feel the vomit in my throat rising up, although I never did vomit. I ve had plenty of doctor trips to my GP who doesn t seem completely sure what s going on, and since then I ve been told to get out of the dark room and sit up right instead of laying down which I have been doing. Nothing has seemed to be getting much better, so the last time I went to see the doctor he sent me up to the hospital for an emergency CT which never went ahead because the doctor at the hospital said a CT could be harmful to my lady parts and could increase my risk of a brain tumour. So I was sent home with pain killers and nausea tablets which do nothing at all. I m slightly concerned about my head and if there is any damage. Am I right to be concerned or am I worrying for nothing?

Hi, You are exhibiting signs of what is referred to as postconcussive headaches within a larger framework possibly of a postconcussive syn Chat Doctor.  The activity you were performing that resulted in your falling face first in the water at high speed initiated the sequence of events which now is being experienced by a migraine-like headache.  I would seek out a TBI specialist or headache specialist (neurologist) to start tracking and properly treating these headaches which typically subside in 3 weeks-3 months.  A thorough neurological examination would be useful in order to assess the absolute necessity for a CT of the head which could be justifiable in your case without fear of cancer in the head or overly irradiating your "lady parts" but I would clearly get a neurological examination first because it is possible that a CT would be superfluous at this point. Hope I have answered your query. Let me know if I can assist you further.
