From 3 yrs ago, until a few months ago, I was virtually bed to couch...I ached at the thought of going more than one block...have smashed up joints because a SUV hit me and took off...I am not one to sit on the 'pity pot' too long, but the pain was unbearable...did the recommended...PT, accupuncture, Chiro, pain management, with little to no relief...then I started walking...first a block, crying in pain...then 3...and now, I can 'manage' 2 1/2 miles...I have to stop and stretch, but I am out there again, hoping to recapture some of my lost strength...it is clearly one step at a time, and no excuses to skip a day, as the pain comes back very quickly...so start walking...it is free and requires only the bravery to feel better...best of luck and pray for me that I make my goal of 4 miles (I used to run 8-10, danced and was on a volleyball team before the accident) while I am still on this planet...thanks, Jackie
