Lingering pain 4 weeks after flare up

It has been over 4 weeks after my 2nd flare in 16 mos…my energy has come back for the most part but I still experience nagging pain in my lower abdomen before bowel movements that persist until my colon is clear. My gp prescribed bentyl 10 mg when needed and it has seemed to resolve some of that discomfort and pain but is this somewhat common? I have not had loose bm, blood or fever.
