Infecteda tragus piercing?

Well I got both of mine done in mid May, and for a week mine were never swollen until randomly one would swell up so bad for no reason and then go down. But they could be sore because they take what seems like forever to heal. My piercer told me that with any cartilage piercing you should expect that "white" stuff because that means its healing. The blood could be from changing the piercing multiple times, my tragus does the same thing when i accidentally hit it or lay on my side wrong while sleeping. But whatever you do, don't take the piercing out because if it does happen to be infected, it won't be pretty. Just keep doing the warm sea salt soaks and rotate the piercing to make sure you get the sea salt water inside the hole. And also wash with antibacterial soap when in the shower. That seems to help with all piercings. Try to keep your hair away from it and wash it thoroughly to make sure that your shampoo or conditioner doesn't affect the healing process anymore. (:
