Hi & Welcome,
Using coke on a regular basis for an extended length of time leads to paranoia & eventually even psychosis. You will never be able to re-capture that euphoria that you're chasing. DominoSarah is right, coke is serious business. It can also damage your heart,& actually causes perforations to form in brain tissue. It can also lead to strokes.
In large amounts cocaine can cause:
Shallow breathing
Seizures
Stroke
Unpredictable or violent behaviour
Twitching
Hallucinations
Chest pain
Blurred vision
Vomiting
Heart attack
Feelings of paranoia, anger, hostility and anxiety even when the “high” is gone
Long Term Effects
Injecting cocaine can cause infections from needles or impurities in the drug. Sharing needles can cause hepatitis, HIV/AIDS or other diseases.
Snorting cocaine can damage tissue in the nose. Over time, snorting cocaine can cause sinus infections and loss of smell, stuffed, runny chapped or bleeding noses, and holes in the barrier separating the nostrils.
Smoking cocaine can damage the lungs and cause “crack lung”. Symptoms include severe chest pain, breathing problems and high temperatures. This can be fatal.
Weight loss
Malnutrition
Sexual problems (like difficulty getting an erection)
Severe psychiatric symptoms including psychosis, anxiety, depression and paranoia.
So, when was the last time you used. What are your feelings/ thoughts around your use? If you want to you can put a stop to this cycle of abuse & reclaim your life. Please let us know how you're doing.

We are here to help you stop this dangerous activity. Your nose isnt what you should be worrying about, death is~
I would assume the hallucinations were related to the coke,as well as any paranoia & obscessive behaviors. But to answer your question, yes, you can have nasal damage from coke, esp with long term use. I am a medical professional, and I have seen this damage. The septum of the nose is usually the site that is affected the most, often causing a hole in the septum which requires surgical intervention.
