Originally Answered: Does getting a tattoo hurt? Is there a age limit for getting tattoo's at a shop?
Well, I think that pretty much everywhere there is no problem getting a tattoo at age 18. The biggest obstacle is usually the cost.
Tattoos on the upper arms and shoulders are amongst the least painful (in my opinion). However, there are always spots that are more painful than other spots, even close by. It depends on the locations of the nerves. Tattooing in the centerline of the body is always quite painful (i.e. center of back, neck, chest), as are the soft, tender spots (near armpit, crux of elbow, front of wrist, etc).
Regardless, the pain really isn't too bad, and after the session, the pain is about the same as a moderate sunburn, and treat as if it were sunburned.
The time it takes depends on the size and detail involved with the tattoo, and the experience of the artist. Some are slower than others. I have much of my body covered now, and I usually go in for 3 hour sessions maximum, no more than once a week. It's hard to go for longer or more frequently. A small simple tattoo the size of a credit card would take less than an hour.
One word of caution: they can be addictive. I started with a tattoo on my upper arm, and now am nearing 200 hours of time under the needlle, with both arms fully sleeved, both shoulders, front piece, back piece and some work on my neck. But I love them and don't regret any of it.
