That happens to alot of people that do coke...i would sneeze for no reason, and we found out that some people add small amounts of fiberglass to coke because they think it gets in the blood faster from the tiny cuts....not saying that happened to you though. I agree with rhirrhi87
Dont use anymore and you will heal. If you use more, you could get a deviated septum, a verrrrry painful experience.
Considering the amounts you did, I'm amazed your nose isn't bleeding more. You have burned and thinned the membranes in your nose. Made some sore spots. They will repair themselves as long as "you don't use anymore". If you continue, it will lead to more damage eventually literally burning holes in your nose which will lead to infections and a host of other problems..Your best bet is to walk away from the coke now. Or it is guaranteed you will regret it later..Thats a fact....
Hopefully you have learned something from this experience, multiply it 10 times, take all your money away, family and friends and job. Welcome to drug addiction. STOP while you have the chance, come clean with the doctor, So what if moms finds out you experimented and saw the effects, Its all part of growing up. We all make mistakes some bigger than others. I would reccomend medical advice, try the health dept or a urgent care clinic , but you have to be honest wth the doctor, they are not there to judge you just treat you. Good luck
I have also considered snorting a small amount of water, saline, or peroxide to cleanse whatever wound I may have created.
