Hi there. My Nana is 93 and normally healthy. She has been on warfarin for the last few months following a DVT (which has now resolved). She has been bleeding when she passes urine since she started on warfarin, and has spotting/frank bleeds on her underwear but this seems to have increased recently. It is bright red blood that makes the whole toilet pan red and splashed with red. Her GP has apparently done a physical examination in the last few weeks, which was ok, and a UTI swab which came back clear. Today when I visited she hasn't been able to sleep for the last 2 nights because she is so much discomfort from her lower abdomen, says she feels confused and generally ill, and was almost in tears. She is very obviously tired, and seems quite pale, with almost a yellow tinge. Her GP was going to see her in a few hours, but should I just take her straight to ER??
