Last time it was preceded by blood in urine (bright pink), then a few days later abdominal pain and severe constipation, unable to pass a stool or eat for 3 weeks. This time, slight fever, I passed a blood clot in urine about 1 cm in diameter and constipation again plus loss of appetite. It's early days yet but I wanted to get in front of it just in case. I took a couple of senna capsules but, like last time, no effect after several hours. I have not suffered any constipation prior to this for at least a year.
The haematologist at home was going to take me off the Eliquis until I told him I was going back to Thailand. He told me to stay on it. I missed one dose a couple of days ago.
edit: After the blood clot I started to take doxycycline (it was 1am) and the there has been no clot since or blood since. It's possible the doxy may be causing the constipation. I have a regular girlfriend, not live in. It is possible I got gonorrhea.
A couple of years ago I urinated a lot of blood and went to ER in Australia. Subsequently they did ultrasound, xray, MRI and cytoscopy but found no issues.
