young23yo female has history of heavy thc use and heroin use smoking has been in rehab for 10 days and is only on risperedone and valium. she also presents with a chest infection and is on amoxcycillin 500mg. has been having bouts of epistaxis for the past week very heavy and lasting for a couple of minutes. Her nose bleeds at all hours of the day and night at any time.Could this be an underlying bacterial infection or could it be from the heavy use of drugs im not sure what to think at this stage or maybe something to do with the lining of her nose. not to sure need a little help here thanks...
