after a 10 minute walk to the gym and a 40 minute workout in the gym, on the return 10 minute walk home,i got dizzy, passed out  and suffered a brain bleed and a concussion on june 5th 2013.  most of the pain has gone except for that in my buttocks and the rear of both legs.  why am I having pain in my legs and buttocks? please have a neuro-surgeon answer this question.
Hi, I do not think a neurosurgeon is available to answer the question as of now. I can tell you why for now. But if you like you can post a paid query to a neurosurgeon of your choice. The cause that seems most likely for your leg pains seems to be ischemia. The brain injury must have somehow caused your brain to act and reduce blood flow to the periphery. Also, since you might have had internal bleeding this might be the cause. The muscle receiving less blood must have necroses or started to die. This is the cause of your pain. Anyway, you should go to a neurosurgeon in person to confirm the diagnosis. I hope this helps you. All the best. Chat Doctor.
