I use pubmed, but the problem for you at home may not be runnning the searches but downloading the articles to read. If you run the searches from a University Library, you will be able to download the articles too.

My personal experience with chiropractic is bad. They can hurt you if they don't understand the underlying cause of the problem. I had a chiropracter scream at me cuz I couldn't relax my back, but the problem was a damaged SI joint and all her pounding on it only inflamed it further. She never bothered to run an x-ray to find out my 3 cm LLD was caused by mis-healed fractures and not an 'alignment problem.' It took a good orthopoeadist and physical therapist to get well.
