Bad back

Friday the 13th didn’t bring me much joy. This morning when getting out of the shower I felt something pull in my back. As the morning went on it got tighter and tighter. By noon it felt like someone was hitting me repeatedly in the back with an axe. After a sleep, painkillers, heat pack and muscle cream it’s not better. Please, Please let this be better tomorrow. I’m supposed to be running in the Los Gatos Great Race on Sunday, not a chance if this keeps up.
