I developed a sharp pain in lower back on one side. Which got worse. Standard stuff didn't help, so an MRI was ordered, which showed a bulging disc in my back, which was pressing on a nerve.
Bad enough, but treatable. The fun was in the time between ordering the MRI and getting it, and then being referred to a specialist, and then deciding on treatment and doing it, it got a LOT worse. Which included not only worse pain in the back, but affecting my hip as well. Badly. And a couple of other spots not directly connected.
I promise you, when you've fallen back into bed a couple of times because when you stood up it hurt too bad, and barely hobbled out of work, 'unpleasant' is an understatement.
The usual treatment nowadays is using an injection of steroid into the area of the disc to help the bulge, followed by physical therapy to help the muscles support things. The injection was yesterday, the PT starts next week. There's a little easing already, so I'm hopeful.
Kevin, during his narration of his liver deciding to kill him, spoke of the fact that, thanks to modern medical knowledge and tech, he's still alive. In my case, not that long ago this would've probably meant some nasty surgery for me; not too many years ago, you were screwed: "Take these pills to help with the pain and we'll try to keep you from getting too dependent on them." Now they prep the injection site, numb it, use a mobile x-ray with a head than can be moved through about 180 degrees of arc to make sure the needle is located properly, inject, put on a band-aid and you go home.
Sometimes the future really is stupid, but other times it's downright nice.
