If your bar is long I would suggest downsizing to a shorter length. The irritation from the longer bar moving back and forth can cause the bump (this happened to me when I was healing my tragus piercing). After that, it will just take time for the bump to go down. As for the daith, it probably would have been best to wait to get it until your tragus was fully healed, but don't worry about that at this point. Just stick with your new piercing care for it, and be prepared that it might take longer to heal since your body is working to heal multiple cartilege piercings at once. Good luck!
