A friend of mine has suffered badly for years with this, due mainly to fast living and bad eating habits.(not suggesting that's the reason for yours!) He tried all kinds of steroids but eventually found that (a foul tasting ) pure aloe vera gel dissolved in water and knocked back 3 times a day has done the trick. Pretty sure he gets it from Holland and Barrett. Not expensive and apparently very effective for that and IBS. Avoids seafood and spicy food as these both cause it to flare up. Hope that helps.
