I've been twice for lower back pain. Doctors seem great and the chiro doctor also great. Leaps and bounds from my last chiropractor. Yes I was sent for an MRI, but not given injections. I didn't ask for strong pain medication but inflammatories (I did get muscle relaxants for emergency). Yah the muscle relaxants are terrible- sleep all day. I don't take them. I guess it really depends on what level of pain. I'm 2 so I find them really helpful.
