Eurghhh... I'm not exactly sure what the inside of a nose is supposed to look like, but that doesn't look good to me. Are you experiencing any pain? Presumably you are experiencing some bad effects unless you make a habit of photographing the inside of your nose to visually inspect it.
Either way, I would advise getting yourself to a doctor, and if possible taking a break from snorting anything to give your nostrils a chance to recover... and I don't want to push you towards more dangerous routes of administration here! I don't mean start injecting, just maybe try oral or plugging or something, this is if you are dependent on something and absolutely cannot take a break... although if this is the case, again, a doctor would be able to give you better advice about your options.
