Severe Nose Bleeds years after Septorhinoplasty, is this a concern?

I had Septorhinoplasty two yrs. ago. No issues at that time. Recently I awoke to a severe nosebleed from no trauma. Two days later I gently blew it and again another severe nosebleed that wouldn't stop so I went to the E.R. They referred me to an E. N T. I am wondering if the Septorhinoplasty is to blame since I never had a nosebleed to this level before the surgery. The blood just pours like a faucet from my nose. Very scary.
