Two large bumps on right side of labia. Feel hard and under skin. Some blood came out of one. Very painful but don't know what they are. Very worried?

Sound like cysts. Painful bumps that develop in the labor are usually cysts. These can get infected and/or inflamed which then causes them to be more tender. I'd recommend seeing a dermatologist to have them evaluated and treated, and make sure they are not something else like an unusual growth.
