Since you have proctosigmoiditis, enemas are a good idea. Suppositories medicate your rectum, while an enema will medicate your rectum and sigmoid colon, so may be more effective. And be really, really compliant with the rectal meds because these are likely the ones that will help you the most.
It sounds as if your doctor is pursuing all the right steps in the right order. If what he's doing doesn't work, be prepared to discuss adding in other meds such as an immunosuppressant (Imuran or 6-MP.) Give it some time, though, three days isn't really enough to know whether your current regimen will work. It can take 2-3 weeks for enough effect to see a difference in your symptoms. If nothing else, this DD teaches us patience.
Hope you're feeling better soon.
