Proving pain and suffering after a car accident can be challenging, as it is a subjective experience that can be difficult to quantify. In a personal injury lawsuit, the person seeking compensation for their pain and suffering will need to provide evidence to support their claim. This can include medical records and documentation of the treatment they received for their injuries, as well as testimony from doctors, therapists, and other medical professionals. The person may also need to provide testimony about the impact of their injuries on their daily life and their ability to perform normal activities. In some cases, photographs or videos may be used to illustrate the extent of the person's injuries and the impact on their quality of life.
