First off, you're only on the first tier drugs so far. You still have lots of medications that you can still try to control your disease. If you're experiencing progressively worse flares, it may be time to upgrade your medication.
You don't mention that you've tried the immunosuppresants like 6MP or Imuran along with other drugs. Then you still have the biologics Remicade and Humira. There's new drugs in the pipeline also that could be approved soon.
Surgery for Crohn's disease is usually reserved for when nothing else works, or for complications such as abscesses or fistular disease or obstructions that won't resolve. Most surgeons won't perform the surgery unless you've tried all other treatment avenues (medications) if it's not an emergency.
I don't know if CD progresses over the years, mine started out severe and every flare has been severe ending up in surgery because the drugs haven't worked for one reason or another. There are many people that have never needed to have surgery and have stayed on the first tier meds all their lives. Then there are the people in between, some with surgeries, some on the higher tiered drugs.
For this flare, your doctor may have to bump you up to Prednisone as it can be given in higher doses which may get you over the acute stage. If not, there's many other meds you can try.
Read some of the posts, but don't let them frighten you. Everyone's disease is different and everyone reacts to the treatments differently. Try to educate yourself so that you can work along with your doctor to find the treatment that works best for you whatever that may be.

49 years old, CD since I was a child.
Six resection surgeries, permanent ostomy, adverse reactions to Remicade, finally off of Prednisone, back on 6MP for maintenance, hoping for a long remission from this last surgery.
