You are saying you still have these things ongoing even after you have stopped using cocaine? Or you get this when you still use it? Is this happening right now? Or are you asking if you will have a permanent issue?
You’re fine. You won’t be experiencing anything like that for more then a couple days at the most.
And if it burns means it’s not good. It’s either meth or mixed with something that doesn’t belong in your nose or the blow. But you’ll be fine
