Do you have any methods you frequently use for severe menstrual cramps?

I am a case where menstrual pain has become extremely severe after childbirth ㅠㅠ

Do you have any methods you use to relieve severe menstrual pain?

In my case, before I get sick... I always take painkillers first;;

I can't just lie around all the time; I also have to work, so the only option is to find ways to reduce the pain.

And in winter, I attach a hot pack on top of my clothes to keep my stomach warm.

Then it hurts a little less. But in summer, I can't even put on a hot pack..

Is there no other way but to relieve pain with medication?

Please try it out and share any methods that were effective in relieving pain~
