Gobles,

A very good friend of mine had two cycling accidents fairly close together. She had a moderate concussion on the first one, that causes her vision to be doubled only when she looks down. After a month or so off the bike, she started riding again. Soon enough, she hit a patch of gravel and conked her head again.

This time, her doc insisted she stay off the bike for a longer period of time. Basically, he told her a concussion is a brain injury, the outward manifestation of which is her persistent double vision. Just like you wouldn't jog on a broken leg, another fall would be/coould be seriously detrimental to the healing of your brain. And it's likely that her second accident was a result of her vision not being quite right after her first fall.

Soooo, she's taken up tandeming with a variety of friends who own them. She trusts them as captains, and can get all the fun, exercise and exhilaration of cycling without having to rely on her own vision and balance to keep the bike rubber side down. She'll go back to riding her single eventually, but in the meantime she can still ride while giving her brain a chance to heal with less likelihood of a fall.

I don't know if this is an option for you or not.

Regardless, I hope you heal soon!
