Tell me about the changes brought about by your frequent drinking of hot water as a girl?

Junior year, tortured by menstruation for two years. Sometimes it hurts for many days and may last until the end of menstruation. And now the pain is twice that of high school. Now it's not just stomachache and simple diarrhea, but also retching. I can't spit anything out. I went to see an old Chinese doctor before, and he said that the pain made my stomach shrink. Then take medicine to recuperate. I have been drinking hot water since last winter. Then now my period is not particularly painful, sometimes it hurts badly. But things are getting better. I used to love ulcers, and I had several every month. Then I insisted on drinking hot water and it didn't grow after that. Oral ulcer is really a particularly distressing thing, just like I love spicy food, so I can't eat it for a few days. This is a more obvious change than menstruation. Probably because I hate hospitals, I have been enduring the pain caused by menstruation. But really, at least after I kept drinking hot water, I didn't have too many colds or oral ulcers. The symptoms of menstruation are sometimes relieved and sometimes repeated.
