I don't know about mind-body connection and the coccyx, but if I hurt my tailbone I would grab the stool softeners ASAP, eat safe foods, drink a lot and try to not take pain killers.
-------------------- IBS-A for 20 years with terrible bloating and gas. On the diet since April 2004. Remember this from Heather's information pages:
"You absolutely must eat insoluble fiber foods, and as much as safely possible, but within the IBS dietary guidelines. Treat insoluble fiber foods with suitable caution, and you'll be able to enjoy a wide variety of them, in very healthy quantities, without problem." Please eat IF foods!
