Please Can You Answer The Following.....I Have Unusual Discomfort In

Please can you answer the following.....I have unusual discomfort in the area below the navel and above the publc area (much like I experienced 20 or more years ago when ovulating)....sort of a pressure-type feeling like a gas build up. Since I'm 71 yrs. old, have had a hysterectomy back in 1996, I'm concerned what this discomfort indicates. Thank you for any light you can shed upon this.
