Wrapping Heating Pad for Pain... https://www.amazon.com/dp/B08DV46XQ5?ref=ppx_pop_mob_ap_share
I take half a cap of miralax and half cap of metamucil, both generic with water. Also magnesium.
Before BM lube up to ease the BM. I use vaseline.
I have a theory that poop stuck along the fissure causes inflammation and pain which catches more poop, so cleaning after BM is important.
I wipe off the vaseline, then poke up with baby wipes. Then fold baby wipes and dip the pointed corner into hand cream and keep poking it up until it does not come back brown, if you can.
Then I squirt warm water up there to clean more. I use a sitz bath with a squeeze bulb to squirt up water.
I find that heating pads work better than zitz bath for pain.
Narrow ones work best for me.

I use base numb, 5% lidocaine for pain. Also calmoseptine.
Care to point out any particular brands/models? I'm leaning toward this https://www.amazon.com/Wrapping-Comfytemp-Electric-Settings-Auto-Off/dp/B08DV46XQ5
This one is larger but looks pretty flexible https://www.amazon.com/MIGHTY-BLISSTM-Electric-Heating-Cramps/dp/B07G2M1LBW
I first thought yo meant the heating pad was too big. Oops. I now know you meant it was a huge help. I did find a smaller one I liked.
