My mother today got blood from head, not no the exact reason she is saying that she was doing combo n suddenly she realised that blood coming from head then within a second she put her head under the tap of water. Her head a little swelled up in that area as like when we got hit up by wall. I m also attaching the click of injured area. Pls suggest wat is it. Hope this is not serious as she is having diabities too but in control condition.
