sores inside nose along with sore throat and headache

PLEASE HELP...Hi, about a month ago I noticed a sore inside my one nostril and I thought it was a possible cold sore which I have NEVER had in my life. I let it go and thought it would just go away on own but felt so bad as if it was going to go through my whole nostril! I ended up using rubbing alcohol on both inside n out and that seemed to help scab it. It eventually shrunk in size n pain subsided major but i kept feeling a small discomfort like a small scratch. I've been also getting random headaches with sharp pain right down middle of forehead and sometimes in temples as well but thought it may be bc i've been under some stress. The past week i've had a sore throat and hoped its just a cold i'm getting. Well today I noticed my nose was really sore again n thought that thing was coming back but it was at almost tip of my nose so I pulled tip of nose up to look inside and as i did, i noticed i had a small off white filled sack inside at tip inside, another larger open sore on same side but against face that i never felt. Then as i kept pulling up to look i popped the small sack and also noticed another small sore bleeding on other side as well! I don't feel sick but have a sore throat. Has anyone experienced anything like this? I began to google it but it led me here..thank you
