I got the tattoo on that particular spot because it doesn't "mirror" my affected leg. I figured that I was having pain anyway and my brother said that it would give me relief. It only hurt when he put the initial needle in...the music was my choice and I picked bands that I liked and never even heard the needles. At the end I had to sit there and wait because I was totally high from the endorphins...
My left leg and right arm are the only limbs involved,so I decided to take the plunge...It really was a great experience. I was soooo prepared to come home and take some pain meds, but I didn't have to. It felt like a great massage, because of the amount of needles. I have had no side effects, except it gets a little dry and I have to moisturize it a lot.
