Change in IBS sumptoms

I have had IBS for many years but have been controlling it very well with a low Fodmap diet. However I have had a pretty bad flare up for the last couple of weeks. I seem to have IBS C whereas I used to get IBS D in the past. I’m using a bulking agent for the constipation that’s not working very well and a peppermint oil for the pain The pain can be very severe and is spread all over my abdomen even right at the bottom just above the groin and there bloating and nausea. Should I consult my doctor?
