I Am A Female And I'm 55 Years Old. I

I am a female and I'm 55 years old. I have sharp pain in my pubic area at times. It seems like it happens when I'm constipated. Also, I have to urinate a lot and when i'm experiencing this pain it hurts to use the bathroom, move around while sitting and move at all. Yesterday while shopping I was having a hard time just controlling my bladder and then later I felt like I was going to faint, my face got hot and I had to get to a bathroom quickly.
I had sharp pain in the pubic area a lot after that and was very fatigued and sleepy. Today the pain has not been as bad, but my stomach hurts when I eat anything.
