Flare-ups are rough; the pain that is felt is exhausting, you want to curl up and hide forever and just want it to end, but it's just another one of those horrible side effects of endometriosis. There are ways, however, to get some relief during a flare-up. First, I should probably talk about what an Endometriosis flare-up is. An Endometriosis flare-up can manifest in many ways. For some, it is an Endo belly, and for others, endo belly is just a normal part of there daily Endometriosis struggle. An endo belly is when the stomach becomes swollen from bloating and inflammation. It looks like you are pregnant, and it's very uncomfortable, to say the least. Flares also can take a toll both physically and mentally. It can feel like somebody is carving your insides out like a pumpkin with a knife that is on fire. They can also cause you to not be able to walk, work or go to school. Make you so tired that you sleep all day and make your whole body ache from the top of your head to you
