Burning is normal, I can understand that. But I've got tatoos, and they never hurt this badly. Tatoos just felt like some one putting out a cigarette on the skin, but the pain's gone immediately, as soon as the needle leaves your skin. This 'sting' was so much worse, so intense!, and I am able to withstand pain very well, compared to other people. This is definitely a 'lesson learned' thing. Will definitely NOT happen twice in my life time!
