Dr. David Lee is the go-to chiropractor for me! I have had back issue for years. Instead of keeping on giving me adjustments endlessly, David actually explained to me the problems and showed me where I need to strength my muscles, so that my body naturally maintain good posture. When you have back pain, the issue is not with your bone necessarily, it has to do with the tissues and muscles that support the bones, so correcting bone alignment won't solve the problem, because your bones will just get misalignment again with out proper support from tissues and muscles. Anyways, David would explain it in much better terms, I'm not doing it justice.
