Hello, Thank you for posting your query to HCM. The bladder infection in very rarely causes bleeding in such amounts to be visible with the eyes. The most common cause of visible bleeding is menstruation or hemorrhoids (the veins around the anus get swollen and start bleed). The second option might be your case, in my opinion, but a vaginal and rectal exam can determine it better. My recommendation would be to consider a visit to your local doctor. He will perform the labs to see if Lupus is under control. will also do a Urine culture, to decide who is the best antibiotic that will take effect for you. With a gynecological exam he can determine where is the bleeding coming from. Meanwhile try to take plenty of fluids, and have a healthy diet. Hope I have answered your questions. Let me know if you have other questions. I will be happy to answer. Take care. Dr. Klarida Papaqako.
