What are the hardest injuries to prove in a personal injury case?

Injuries with primarily subjective or fluctuating symptoms can be especially contested. Examples include some soft-tissue injuries, concussions, chronic pain, headaches, post-traumatic stress, and conditions without a clear finding on routine imaging. Pre-existing or degenerative conditions can also create disputes about what the incident caused or aggravated.
Difficulty does not mean the injury is unreal or the claim cannot succeed. Prompt and consistent treatment, appropriate specialists, diagnostic testing, documented changes from the person’s prior baseline, medication and therapy records, and testimony from family members, coworkers, and qualified experts can make the effects understandable and credible.
