Pain management advice

The abdominal pain has become nearly unbearable in the past two weeks. I’ve been diagnosed nearly a year. I have not yet been prescribed anything to treat the disease but have been giving many different pain killers and short-term steroids to try get it under control. Nothing has worked but until now it has been just about manageable. But now, the pain has gotten out of hand. I’m not in the position to go to the hospital or see a doctor in the foreseeable future (thank you waiting lists!). Does anyone have anything that has worked for them? I’d take or do nearly anything at this point that allows me to sleep a full night or stop constantly thinking about the pain that I am in. Any advice is appreciated. Thanks!
