Yesterday And Today My Urine Won't Flow. This Morning I

Yesterday and today my urine won't flow. This morning I was pleased to get maybe 1/4 cup max. The urge is there but when I stand or sit nothing (generally) happens, There is a burning sensation in the pelvic area that gradually subsides. The urge returns within a few minutes and I go through the same routing.

I might mention that at this time of the year I have a strong allergy to yellow pollen and sneeze a lot w/ coughing and watery eyes. When the allergy continued, with the urinary thing starting I got an OTC product that is compatible with the Warfarin I take. The product seems slightly effective . The urinary symptom is about the same at the end of the third day of discomfort. Today I drank the equivalent of three 12oz bottles of water. No food until light to medium supper of salad and pasta. Also, cough doesn't "produce" if lying down. I need to sit or stand and get "product. Otherwise cough is merely irritating.Your thoughts and recommendations?
