Thanks to all of you. The support is very helpful.

I am not an *avid* cyclist, but I enjoy it. I have not yet been back on a bike.

My ding-history is basically irrelevant. I didn't play football or lacrosse for significant periods of time, nor did I incur significant dings during that period. In any case, my aim is recovery.

Re: recovery. This is very difficult to deal with--for the reason you say: it doesn't seem like things are improving. I see some improvement from day 1, but not as much from month 1. Until I feel markedly better, it will be difficult to know how much improvement I've made. You are right to remain calm; but then again it is very difficult to not do anything. I'd kill for the chance to go for a run, or even a 2-hour walk--or simply feel well for one day...

Your suggestions are much appreciated. If you have more, please let me know.
