If you're dealing with pelvic pain and bloating everyday and need something that you can wear around and work through chores or whatever with, then I suggest the menstrual heating pad by voligo on amazon -amazon link.

It has an adjustable strap you can wear around your hips, it lasts for about 7 30 minute uses before you need to recharge, and the best function imo is it has a vibrating mode that almost completely relieves the bloating/swelling pain for me.
