I started having severe pain on my right side about 4 hours ago, and blood in my urine. Difficulty peeing, like going through a straw, intense pain when I go, and lower back pain. Toilet tissue is pink when I wipe and definite blood in toilet past three times. General abdominal tenderness, and headache. Sporadic shooting pains on right side. I had a partial hysterectomy 18 years ago, so I do not have periods. This all came on very suddenly. Wondering if I should go to hospital.
