Rib cage are tattoos made as a part of the back tattoo or chest tattoo or it might also be independent of the back and chest. There are many designs of rib cage tattoos for women. The worst part of these tattoos is that getting these tattoos made can be very painful, as a human rib cage has 24 bones, which are arranged in 12 pairs. Tattooing on a bone is always painful, whether they are on the rib cage or on the ankle, but with tattoo aftercare, it will not be as painful. If statistics are to be believed, there are more women, who are sporting rib cage tattoos, as compared to men. It may be due to the fact, that women have more pain tolerating capacity than men.
