So, CH took me to a nearby doctor's office which specialized in bones and muscles. The doctor took a couple of X-rays, and bent my legs around. "Does THIS hurt? How about THIS?" Finally he announced that there was nothing seriously wrong, but I had a lumbar sprain. Gave me some medicine, and
CH left me to go to the drugstore, while I stayed behind for the therapy. First, they had me lay down on my back, with a heating pack under my lower back. I think because I have poor posture, my back doesn't like laying in that position. I was a little bit uncomfortable for the first few minutes, but soon it actually became pleasant. After about 20 or so minutes of that, they came and changed to electro-shock therapy! Two electropads were positioned on my lower back, and the machine shocked me. It was a very weird feeling, kind of like a strong vibrator. In fact, the feeling was so strong, I called them back to lower the setting. That went on for about 15 minutes - the machine went through a progammed cycle of various shock patterns. Next came the ultrasound treatment. Some kind of ultrasound probe was rubbed around my back for 5 minutes. Finally, I received infrared treatment - basically they shined an infrared lamp on my back for 5 minutes.
For all that treatment, you'd think my back would be in perfect shape. I can't say it was, however. For the rest of the day, my back felt pretty much the same. The only improvement I have noticed is that it didn't hurt as much during the night, so I have been able to sleep better. The medicine they gave me consisted of a muscle relaxant, an anti-inflammatory drug, and something for "gastric distress" which the other pill causes. So I can't say if the therapy or the medicine was helping.
I'll have to decide tomorrow whether or not to get more therapy. They only give medicine for 3 days here in Korea, so you have to return. I'll have to decide whether to get more "treatment" or not. I am inclined to say no. My friend JI told me his brother worked at physical therapy hospital, and could give me free treatment if I wanted it. Also, he recommended I try accupuncture first, before returning for more therapy. Finally, I read this quote on the internet about lumbar sprains: "Physical therapy and spinal manipulation are of limited benefit in most patients"
