I just got my cartilage done a few days ago and its red and throbbing but not swollen how can I make the throbbing pain and redness stop? Is this normal?

Yes, it is normal. The swelling is all partn of the healing process. No need to worry, so long as it isn't leaking pus or blood or anything like that then you're fine. It might be painful but just keep cleaning it and I'm sure you'll be right as rain. Xx
