I'm not sure if anyone has mentioned this yet, but it's absolutely essential to drink water, I think 2 Litres is recommended (8-10 glasses of water) per day. Other liquids are good too (e.g. juices). Tea may cause constipation if there's milk in it, milk totally prevents me from going to the washroom! Caffeine is also something to avoid , according to most people.
I've heard that the bathing helps a lot, maybe even more than medicine for some people.
Take care, I hope you find some relief soon It's not an easy thing to deal with.
