Herb's no doctor - and I don't see mine until Wednesday - but I was freaked out anyway.
Exercise is a good stress reducer, so I decided now was a good time to get some. I took off on a rigorous walk, determined to see how hard I could go before I started hurting. I did 3.19 miles in 48:27 , a brisk 15:11 pace. The best part is that I experience very little discomfort, and what there was was mostly in my ribs, which I now realize are not yet fully healed, although getting close.
With luck and the right exercises maybe, just maybe, I can avoid the dreaded pin. -- Rob
