When I've been drinking recently, I've sometimes been getting nosebleeds either then or the next day. It's not like blood pouring, more like needing to blow my nose and blood being on the tissue. It doesn't last long. I've also been often getting a severely runny nose, though the bleeds don't always coincide with the runniness. Does anyone have any idea what this might be, and whether it's potentially a cause for concern?
