Hello, 
From your medical history, I think of possible fragile blood vessels in your nose. This might cause you 
nasal bleeding (
epistaxis). I suggest consulting further with 
ENT specialist for further evaluation. 
For the moment, I advise to monitor your blood pressure (bp) and record the results for future reference.
Discuss with your caring doctor about my advice and ask to run a few diagnostic tests:
- 
complete blood count to rule out anaemia
- check iron levels and deposits
- measure 
vitamins like Vit B 6, 12, C, D, calcium, etc. to rule out related deficiencies.
When you have a bleeding episode from the nose, should bend downward with facing the ground. Apply pressure on your nose , on the area when the hard bone starts. 
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Albana Sejdini, General & Family Physician
