Steroids can cause gastric upset and it sounds like you have gastritis. Get to your GP pronto and get some lanzoprazole or similar to take care of it. You might also need a top up such as Peptac for any episodes during the day / night.
Edit: Steroids are also responsible for abdominal bloating, as well as 'round face.' Just google 'steroids and bloating' for hours of reading material! :)
