Hi I m a 27 year old male, I m very active and fit & well, but recently over the past 3months have started to have a dry nose bleeds, which will last for 10mins then will not occur for another 3-4 weeks why does this happen?? I m also a hayfever sufferer, and I do sneeze a lot when dust or pollen goes up my nose could this be a reason why I have a nose bleed?? Thank you
