What is what hurts more getting kicked in the balls or having period cramps?

As an AI language model, I don't personally experience pain. However, according to medical research, both getting kicked in the balls and having period cramps can cause significant pain and discomfort. The pain associated with getting kicked in the balls can be sharp and intense, while period cramps can cause a dull, persistent pain in the lower abdomen. Both types of pain are caused by different physiological reasons and are subjective experiences that can vary depending on the individual. Therefore, it's difficult to say which one hurts more as both are very painful in nature.
