I am a newbie, I injured my head in a horse riding accident. I was wearing a helmet but have done some damage to my head. I am 9 weeks post concussion and still have a constant headache. I am on meds for pain control.

I was 3 weeks away from my first international competition with this horse and I want to stay as fit as possible so that my return to the showring doesnt take as long. My dr has said that if I take a high enough dose of the pain killers and cant feel the pain I can go back to riding.

I have sent my horse away to a trainer until the neurologist ok's me to ride again. I attempted walking yesterday and I am ok on the flat but walked up a long flight of stairs and it got my heart rate up and left my head feeling worse. As per my Dr who says I can go riding this is ok but I just thought I would ask what you all think while I wait the next two weeks to see the neuo.

How much exercise can/do you do? Is there something that is better than the other to stay in shape? Yoga?
