Cocaine snorting causes nasal congestion
and it may cause inflammation of nasal mucosa. Due to congestion blockade of nasal tube occurs some times. Due to this you are having feeling of blocked ear. There may be some crusts formed in nose. So I will advise you to not to take cocaine again and visit an ENT doctor for proper evaluation. You can take anti histaminic drugs for symptomatic relief.
