I've had back pain ever since I could remember. But this past couple of months....actually I would like to say it's been a year in a half, I've had this weird spasms or jerks on my lower back area. If I just stand up for a minute or even for a few seconds after sitting down for some time, I get this terrible pain when I sit back down. I get the spasms when I'm laying down in my bed and then when I stand up just for a little bit, I get the spasms in my lower back area of the spine when I lay back down. I'm 15 years old and I've had Scoliosis ever since I was little. January of this year, I went to my Pediatrician and he checked my back and he said that my Scoliosis was actually worst than my sister's when her situation was the worst. Sometimes the pain is excruciating but I don't feel the need to scream out in agony. I just let the spasms die out until I can move around. It's very aggravating to say the least. What could it be? Is it related to the Scoliosis or is it it's own separated problem?
