No, we do not feel pain after death. Death is the state of permanent cessation of all vital functions in a living organism. Once a person dies, their body and brain no longer function, and consciousness ceases to exist.
Pain is a sensation that requires a functioning nervous system and brain to be experienced. When the body dies, the nervous system shuts down, and the brain ceases all activity. As a result, there is no consciousness or awareness to perceive pain or any other sensations.
It's important to note that there are various beliefs and cultural perspectives on what happens after death, including notions of an afterlife or reincarnation. However, from a scientific and medical standpoint, once death occurs, any capacity to experience pain or any other sensations has come to an end.
