Hi,
First I would like to add your very strong willed to stop due to this for I? I would crush percocete, vicodin oxycontin and sniff this for about 3 years str8 I blew my nose one day and out came blood, I called talked to a nurse who told me my nose could collasp, other internal injuruies, scared me then I still would use this way.
OK I am no longer using On Methadone no cravings cause of the Methadone and hope soon to be off this...
Get a apointment in with your primary care doctor and see a nose and sinus doctor tell the truth and take it from there for and yes damage could still go on after you stop many things can happen like a infection that you will not notice that even antibiotics can not take care of, you may have to have your nose and sinus cavities scraped and cleansed this is to save your nose and sinus from further damaghe and more so? yes it will hurt, but please get to a doctor fast that is theonly way you will know.
