another thought on this is it is not just a pentagram that represents wiccan energy.

a five pointed star is also the symbol for femenine energy.

so lets reach a little and look at the possibility that maybe you have been using more of your male sided energy and the pentagram when you placed it on your body empowerd some of your femenine energies. thus being a strong energy you would feel.
couple that what the symbolism that you hold with the pentagram anyway.... and you get a double dose of feelings from it .

If you have been using more male energy which i think is the right side of your body and femenine is the left side of your body you would indeed have a strong reaction . . Most of us are being led to use more of our feminen lately. and to integrate our sides together to find our spirit core.

Okay just thinking out loud and on paper. lol when i see a pentagram my first thought is not wiccan it is the divine femenine.
may not hold any truths for you just throwing it out here so it might prompt more thoughts from others to maybe help you
