It all started the day after my first non-commute road ride in about a month. I have a fairly aggressive geometry on my road bike, but it's never caused me more than a little stress in my upper glutes / lower back. Perhaps it was the cause? Regardless, there was no way I could get back on the bike with the amount of pain I was experiencing. I hobbled through the week, grimacing throughout the Christmas holiday.
On Sunday, I was feeling better. I saddled up again, and went for a 40 mile ride. I took it easy, but could feel every pebble on the road. I rode up tiny little Moss Hill, which is pronounced enough that a town is named for it. Whether on a flat or on a hill, my back was tight. I couldn't get in the drops for more than about a minute. Once home, my back was hurting again and the periodic spasms were back.
And then suddenly, about an hour before bed, something changed. I noticed I wasn't in pain. A little sore, a little stiff, and a bit twingy, but not really in pain. And this morning, it felt even better. So was the ride the cause? The solution? Or just your typical back pain mystery? I think I'm going to find a chiropractor in case I need urgent services in the future.
