I have damaged my nose from cocaine use. When looked inside it appears to be burned. Whitish green patches along septum to deep inside used polysporin (bacitracin and polymyxin)?

Need examination. The body's very resilient. First & most importantly...tell me about your intention on doing any more damage to your nose if you get this one fixed? There may be nose transplants available by plastic surgeons these days but do you really want to go that route? Your ulceration problem may need more aggressive treatment strategies. Also, you may further damage things if you self treat. See your DOC!
