I went to a chiropractor for neck/whiplash injuries and what he did actually masked the true source of my pain (not spinal at all), and seemed to have made my whiplash recovery slower. Maybe I just had a bad chiropractor, although he was recommended by several people. So I hesitate about going along with the recommendation to see a chiropractor.
I would recommend that you find a weight lifting coach who understands your issues and can teach and supervise your lifts in person. Written and video instruction is no substitute for having someone watch your form in person--and your back is too important to take risks.
You make your choices, and you live with them. In the end, you are those choices.
