Hi . Hope everyone is having a good day. Today I wanna open up to something I've never told before. Plz help without judging. I'm 13. I don't have any close person and my connection with my mom is very bad . So I only have here to post . I've been experiencing this weird thing , it's like I feel like there's something down there , in my intestines . Every month I get a very sharp pain in the bottom of my intestines. I could go a whole night without sleeping becuz if it . I searched how to know if u have worms in ur intestine and this is one of the symptoms. Plz I need help . What way can I tell my mom about this ? What are the treatments ? How dangerous is this ? Thanks a lot .
