I'm 37 weeks pregnant, my feet are EXTREMELY swollen to a point I can barely walk. I have a hardened lump at the bottom of my belly that is very large and is so tender to touch (it is not the baby is is like a pitting fluid) what could this be?

Without examining you, I can't tell you what it could be. However, you mention that you are swollen. What has your blood pressure been like? Can you take it from home?
