Hi I'm 56 Yrs. Old, Female, For About A Month

Hi I'm 56 yrs. old, female, for about a month now I've been experiencing an over active bladder, I have not been able to hold liquids for very long, its at the point now, if I'm driving for any distance I watch what I drink and I stop my liquids at a certain point at night now, I know I'm get to that age that I should expect that, but this came on sudden within the last month, usually I would drink over 32 oz's of water while at work and not have to worry about making it to the bathroom, also along with that I'm experiencing heaviness in my legs, I don't exercise a lot but I do walk quit a bit I've made an appointment with my PCP I wondered if you had any specific questions I should asks
