a few posts before this you said that you added tape every other day or every third day, and that you added enough tape to go up a size or two. that's going waaaaaaaaaay too fast. if you're currently at 8g it should take you at least 14 months to get to 0g, assuming you stay at 8g for a month and let your lobes heal (I personally would stay at 8g for at least 3-4 months before stretching further). so you should be taping once every month at most, and only adding a fraction of a millimeter to the size of your plugs each time you tape.
also, keep in mind that some people can just add new tape with no problems, but some people end up getting overly sensitive to materials they wear for a long period of time (plus the fact that the build-up of dead skin can sometimes cause problems). so if your lobes start getting sore or raw and you haven't taped up recently, I'd try removing the tape, washing the plug and re-taping it back to the correct size.
