21 years old, suffering from mysterious mid-low back pain for 8 months constant. Got worse instant, still goin?

could be multiple things wrong. If you are having foot problems, that can severly affect the back. I would recomend some custom made orthotics to give your back some support and allleviate your foot pain, most chiropractors and podiatrists can help you. you could also have a chronic strain that won't heal. You shoudl investigate Manipulation under anesthesia to help alleviate that, after you have orthotics and some more tests done. Check out the link on my website that will give you more information on that, http://www.villagefamilychiro.com click on manipulation under anesthesia on top left, let me know
