What could be the association between small bowel obstruction, hemorrhoids and swollen dry skin?

Bowel Obstruction: It's possible the hemorrhoids were there before and the increase in the abdominal pressure when the bowels were obstructed caused the hemorrhoids to "flare". Small bowel obstructions can cause a diversion of body fluids to the abdomen, which can cause the dry skin. I'm not sure exactly what you mean by swollen skin....But it's possible to have lower extremity edema in this situation as well.
