I'm 36 yrs of age I am on my period last month I had it twice it's always heavy and I get a lot of cramping but this months has brought an new painful muscle spasium on my vagunal lip walls it stops me in my tracks it hearts so bad it dose'nt happen when I pee only when I'm moving around or just sitting and relaxing. I have never had this happen before. I took a look and don't see any lessons or bumps but it is tender to the touch though.
