Getting a tattoo is no walk in the park- it can be downright painful. The armpit and rib cage are two of the most sensitive areas on the body. So it's no surprise that getting a tattoo in either of these places can be extremely painful. The skin in these areas is thin and delicate, and the bones are close to the surface, making it difficult for the needle to penetrate the skin without causing discomfort. Furthermore, the armpit is a highly vascular area, which means a lot of blood vessels are close to the skin's surface. This can make the tattooing process even more painful and increase the risk of bleeding and bruising. If you're considering getting a tattoo in either of these areas, be prepared for some severe pain.
