I am having lower abdominal discomfort, heaviness in my lower abdomen since the last two days. There has been an increased tendency to urinate too.It is the 3rd day today with other symptoms getting better but have a little radiating pain in the lower back left. My urine is clear, doesn't have any smell, or burning/pain. Please suggest what could be the cause. I was checking the symptoms and wyas worried. The symptoms started Sunday Night.
