Should I try Prune Juice? Pls read my situation.

First important thing to note: I have ibs-c

On Sunday I thought I had the stomach bug because I vomited and had diarrhea (and had cold symptoms). It definitely cleared me out a lot. Eventually, the bowel movements stopped but the cramping and gas continued. It felt like there was still more but it couldn’t come out.

Now I’ve been constipated since Sunday night (4 days). I often am constipated this long but I’m not usually this bloated and in pain! I could wait until tonight, take senna, and hope it works in the morning, but I’m in so much discomfort. Eating more hurts me.

That being said, I’ve never tried prune juice but I’m considering it. What scares me is that it can cause MORE gas and cramping. Should I try anyways? How much? If i drink more water before i take it will that help with the gas/cramping?

Edit to say: my gas pain is really bad :(

Thanks for any advice!!!
