Well you should not be in pain at all, if you are lathering the ointment on it then you may have caused this yourself, it needs to breathe still. I’d pop to the docs and get some antibiotics, let it dry out now and see what happens, just leave it alone, you won’t lose any colour at this point of healing if it is left to do what it wants to do. Aftercare of a tattoo is pretty simple stuff, constant handling and cleaning is not good for it. Follow the initial Vit E for a week or so and then leave it alone, keep it moist if you like but should be well on the way to healed within a week.
