Last week I ended up going to the ER due to back pain. I thought that maybe I had a kidney infection, which is why I went to the ER. Turns out that it was back pain due to my bulging disc and muscle pain.
I've never had a muscle spasm in my back quite like that before. It was like having a charlie horse along my thoracic and lumbar spine. Luckily steroids and non-steroidal anti-inflammatory cleared up almost all of the pain. I can move again! : )
