I'm thinking that I'm definitely not gonna do that.
It is actually a pretty standard treatment: http://www.prevention-center.com/surgeries-en/scar-treatment-en#Scar treatment with cortisone
I've injected all of my scars with hydrocortisone, and had great results. Even a rather nasty one inside my lip from a skiing accident. The tougher ones just take a few rounds of injection.
I see no point in paying a dermatologist $80 to do something I can do with a $0.30 needle and a $5 vial of cortisone from an online pharmacy.
Granted, I also surgically excised every mole over 2mm on my body a few months ago for cosmetic purposes. I might be a bit cavalier on DIY medicine.

Price of playing the game unfortunately.
.. My esxpsierince as well as many others experiences I know is that the scars will first fade to the collar of the skin and then smooth and soften over time. If you have any abscess marks they will probably remain visible for a while, but over a relatively short period of time you scars will fade from the darker shade the are most likely now to the shade of your skin.. and if they are raised or rough they will flatten and smooth out to become something hardly noticeable at all. If you want to see an example look for an older scar you have from something you rememebr in your childhood, you will likely be able to bareilly see a slight slight discoloration where the scar has basically disappeared back into the normal skin. So in other words I wouldnt worry about this much, and please dont use it as a source of guilt and shame, guilt and shame just drive use so please throw the guilt and shame in a deep part of the ocean and instead focus on the pride you should have about the steps you are taking to get clean.. In a couple months you tracks wont be that bad anymore and you will be able to start wearing short sleeves and they will continue to heal and disappear until only a very close inspection will reveal anything. focus on healing yourself and dont worry about the track marks as they will fade and disappear.
