Proctitis is giving me hard time again

For a week, my proctitis has been acting up. My GI told me before not to take more than one colifoam per week. I can't. I took 2 last week and they couldn't control my symptoms. Things became worse yesterday. I have shooting rectal pain, muscle ache, severe headache and nausea. This happens to me when my proctitis acts up. The horrible thing was that my mum woke up from my burping. I was burping with a very loud sound. She woke up though I was downstairs.
I took pentasa suppositories but I had to rush to the toilet after 2 hrs (before I could retain it for 8 hrs). In the morning, I took colifoam but I'm still sick. My friends had booked us a concert but I couldn't go because of pain. I can't sit down.
Before getting my fistula, I used to take 2 pentasa enemas and 1 budesonide enema every day and they managed to put symptoms at bay. After fistula, I can't retain any enema; it comes out right away. Any suggestions what to do? Usually, when I had these symptoms, they wouldn't last for more than 2 days. It's very long this time.

You're right. I was mistaken. He said whenever you are in a flare up, take colifoam daily until it controls the symptoms. Remicade is the first biologic I'm trying.

Andrina, thank you so much. Yes, it has. The only problem now is the fistula but I'm trying to cope.
