question: Hi, when I was 10 I was jumping on a trampoline I hurt my lower back. I was in bed for several days. Today, be it the way I sleep, or using the bathroom ( stool ), I hear my back pop, and I have trouble standing and it makes my entire body week, where I feel like a noodle. This is the only time I can recall ever hurting my back. I m unsure what to do, as it seems like the injury (15 years ago) is too old to treat?
