Last Wednesday afternoon I tweaked my back again and was terribly uncomfortable (lower back-related-spasm activities). Thought it was going to be all better yesterday, felt pretty good all day. Sitting in my desk I twisted a bit and felt like I'd been hit by lightning, followed by a general re-clenching of the back muscles that'd just been insulted.
So, that was really painful. Bad enough that I begged off work the rest of the afternoon and set an appointment at the doctor's office for this morning.
The usual prodding plus a spinal x-ray later, they sent me off with a scrip for something to release the spasms. I am hoping that will set things right.
