I am constantly peeing a lot is it because i had a partial hysterectomy 7yrs ago or is it a symptom of a cyst on my ovary ?

You'reASweetPerson!: Wrong organ.And,no it isn't your piano.It may be your pancreas (the organ,among others,that helps regulate your blood sugar).That's the first thing to worry about so go get a blood test or at least get a drop of blood from your finger tested for high sugar.There are other things that may cause this fountain of peeing(including drinking lots of beer or coffee)but check the sugar first.

Check with your DR: if you are going to the Bathroom frequently, then you need to check for urinary tract infections and diabetes.
