Weird man. I believe that you are aware that oxycalm is based on oxytocin which is a hormone released by women during labour, which aid in the dilation of the cervix and of the vagina.
I extracted this from wikipedia:
"[Oxytocin promotes ] Various anti-stress functions. Oxytocin reduces blood pressure and cortisol levels, increasing tolerance to pain, and reducing anxiety. Oxytocin may play a role in encouraging "tend and befriend", as opposed to "fight or flight", behavior, in response to stress."
So really, I do not know how you got your nosebleed.
Sorry, maybe I was just useless, better wait for someone more knowledgeable.
