I do sympathise.As a fellow sufferer it can be very miserable.
Have you tried eliminating certain foods?,Dairy food triggers it off with me ..in others it is wheat and gluten.I no longer drink milk and although I love cheese ..I just know it will upset me.I still eat it though !! But..it is mainly milk that triggers my attacks.
I use soya milk or Oatley as a substitute.
Peppermint or Camomile tea is nice and helps to settle the stomach.Also milk thistle which you can get in any health shop. If you suffer from gassiness, eliminate beans, cabbages, and other "gassy" vegetables from your diet.
Try to avoid stress.A hot water bottle on your tum will ease the cramping and aching. Regular exercise, such as walking, can reduce stress and encourage bowel movements if you are constipated.I hope you feel better soon..Good luck.
