Question: I need to urinate every 15 minutes…now using my mother’s diaper

Sudden onset of frequent urination literally every 15 to 20 min and after about 7 hrs of this and having to use one of my mothers diapers I notice there is a pink tent on the diaper this is with no pain. I normally keep myself well hydrated by drinking 8 to ten glades of water a day but for the past few days have needed almost double that amount for unknown reason unless it is the sinus dds I have had to take for the last several weeks terrible sinus drainage to the point of having to sit up to sleep or drown!!all over counter meds as I do not like prescription meds what can e causing this??
