I got the same effect. Usually happened at night but sometimes during the day. Keep your finger out of there.
Put some Vaseline or A&D ointment on a Q-tip and rub it inside your nose to keep it moisturized.
Get that blood pressure checked, mine rose from 126/76 to 168/72 while I was on it.
You can also look into having the blood vessels in your nose cauterized.
Hope this helps.
