Hey everyone, thank you in advance for reading and really any advice would be so appreciated here!
I am 21 years old, 5'10", female, 137lbs, and an active long distance runner. I don't have any major health issues besides asthma but I've been struggling with lower back pain on and off for years. I have very mild scoliosis but according to my GP that shouldn't be causing me any pain. Also (and this may be silly but I'm really at a loss) I follow a really strict nutritional routine so could this be the result of some kind of nutritional deficiency somewhere?
In general I have a fairly constant ache in my lower back, nothing that prevents me from maintaining a high level of activity though. But if I have to bend over for anything more than a few moments (to clean the tub or change a tire on my bike for example) I find it difficult and VERY painful to stand back up straight. Sitting for any period of time causes the same level of pain and I have to constantly change sitting positions. It is almost impossible to get comfortable unless I am lying completely stretched out, which makes working, sitting in class, going to a movie or a restaurant an awful time for me. Also, I am sure to maintain good posture when seated so I don't believe slouching is the issue.
I often wake up with this pain as well and am unable to get back to sleep or make it go away afterwards. Sometimes I get it when I'm standing for long periods of time as well but bending and sitting definitely trigger it the quickest. Oh and exercises like sit-ups and crunches cause me severe pain as well.
I'd really appreciate some advice here. Should I see a specific type of doctor? Pain killers do nothing to help once it gets started and I'd love to be able to put off this severe lower back pain until I can at least blame it on old age or something!
