Sulphur/rotten egg burps, nausea, pain

I've only ever suffered with this once in 2011, before I was diagnosed with UC, and it was horrendous - I was bed bound with awful pain, I had very bad diarrhoea and sickness and the burps were coming thick and fast.

Yesterday I burped and it tasted like rotten egg. I thought to myself no way it must have been something I ate with eggs in but lo and behold I've woken up this morning with 'the burps', excruciating stomach pain and nausea. I haven't vomitted, only dry heaved once, and haven't had diarrhoea. I passed a small stool this morning but it was an uncomfortable one, quite gassy and separated - if you see what I mean.

I have an incredibly important job interview tomorrow morning for my dream job and I am so stressed that this is happening the day before (again, it's only ever happened once before all the way back in 2011!).

Does anyone have any idea how to remedy this?

Add on: It is my personal opinion that you are so inflamed inside that it is causing constipation and this issue as well, hence my thoughts that your GI really doesn't know what he is doing because you both seem to be ok with under treating your condition and allowing the severe inflammation to continue. Taking one 400mg of Asacol nine times per day is beyond stupid, and that's only a total 3.6 grams per day when the max dose is 4.8 grams. I realize at one time you thought Asacol was giving you troubles but then found out that apparently was not. Have you had a recent colonoscopy and had your CRP levels checked? You mentioned doing enemas and suppositories but didn't mention whether they were mesalamines or steroids. I'm betting that most of the time you don't do enough of those either. Severe inflammation should not be allowed to continue. Hope things went well with your job interview.

I was reading through your old posts because you really didn't give us much of any info to go on. That's why no one else is responding. What are your current treatments (in detail)? When was your last colonoscopy and what were the results? Have you had any CRP levels checked recently? I'm asking because it sounds to me like you are severely inflamed and this is what is responsible for the symptoms you describe. Sometimes you can't just go by your current symptoms to know what condition your UC is in and need diagnistic testing such as the colonoscopy and CRP levels. Your UC may be doing a lot worse than you realize. Let us know how the interview went. Good luck.
