Hi Michael and welcome along to the forum. I find that my p gets red immediately after I've had a bath, exercised or put on moisturiser, though it calms down about an hour or so after. With that in mind, I try to time when I do all of the above, if there's an event or something I'm going to do where the redness my bug me.
Sorry I can't be more help, hope your flare clears soon.
