As far as the most common injuries Plaintiffs suffer from, as a personal injury attorney it is my experience that concussions are the most difficult to document for legal purposes. Apparently, my opinion is backed up by “Johns Hopkins Medicine” because the following is stated on their website regarding head injuries “The full extent of the problem may not be completely understood immediately after the injury”.

Unlike a bruise, or a cut, a concussion can be a nebulous injury
because it doesn’t need to leave behind any superficial evidence
for it to have occurred. This can be
especially true when dealing with injuries resulting from a car accident…
“What causes bruising and internal damage to the brain?
When there is a direct blow to the head, shaking of the child (as seen in many cases of child abuse), or a whiplash-type injury (as seen in motor vehicle accidents), the bruising of the brain and the damage to the internal tissue and blood vessels is due to a mechanism called coup-countrecoup. A bruise directly related to trauma, at the site of impact, is called a coup (pronounced COO) lesion. As the brain jolts backwards, it can hit the skull on the opposite side and cause a bruise called a countrecoup lesion. The jarring of the brain against the sides of the skull can cause shearing (tearing) of the internal lining, tissues, and blood vessels that may cause internal bleeding, bruising, or swelling of the brain.” (Source: Head Injury | Johns Hopkins Medicine)
This all to say, please be aware that you can still be injured without having blood dripping from an open wound, and please follow up and report any symptoms to a medical professional if you were involved in a car accident or slipped, tripped, or fell.
