I am going to start with the fact that I have never been a big supporter of the chiropractic field. Just being honest and want you to know that my opinions are based on care I have seen and received. I will not go back to a chiropractor ever again as the last one caused me long term pain and made my back problems worse (long story).
However, I find massage and physical therapy helpful for my emotional wellness which in turn helps my Crohns status. If it works for you and does not cause any additional pain, it is worth that $35 visit.
