Several of my family members have back problems similar to yours; my sister had back surgery in her late 30s, my mom in her 40s, my brother is getting to the point when he will have to have it, & my dad had 5 back surgeries at Mayo. In addition, I am an RN with experience caring for postop laminectomies.
My advice, is always try the least invasive treatments first. Yes, you're out some $ if they don't work, but if they do work, you're so much better off. Eventually you may need to go the surgery route anyway, but I urge you to try the others first. There are risks with every surgery. Some people have great results with surgery (my mom for example, & many I cared for in hospital), but others don't have such a great result (my sister & dad). You just never know. If it becomes necessary, it becomes necessary, but try to avoid it as long as you can. Good luck.
Healing Touch is another alternative modality you can try, IN CONJUNCTION with other interventions, to increase the chance of success with those interventions (can help to decrease swelling, inflammation, & spasms so that the other interventions work better, & is painless).
