I’m sorry to hear about your week. Taking oxybutynin a couple of hours before my changes helped a lot, but sometimes they were still painful for some reason.
The blood makes me wonder if you might have a stone inside of your urethra, and perhaps the bladder spasms caused it to get pushed further down. I would refrain from urinating until the doctor looks at everything, but be sure to let their office know about the blood.
