For the pat week I ve had this weird pressure in the left side of my abdomen. I assumed it had something to do with me recent prune juice and fiber intake. But every time it happens(always at night) it seems to be getting worse and worse. Tonight it feels like pressure and burning, my sinuses also feel weird (like they are constantly clearing up and I keep smelling a weird smell. Tonight I also have a strange tightness above my right hip, right at the base of the abdomen, and its throbbing. And when I lay down, whichever side I lay on feels like its burning.
