For quite a few years, I get extremely nauseous, light-headed and dizzy in showers. Well, tonight, I had a shower because I was so cold but I started to get this severe abdominal pain. (I am ftm-transgender, but I still have my female parts, so I'll continue with this->) Its right above where the uterus would be. That entire area is constantly bloated and rock hard. When the pain got worse, so did the hardness of that area, which was odd. And my lower back hurt really badly, too.
