What I meant by muscular is actually "soft tissues", meaning no bone injuries. However, just because no bones are broken doesn't mean there's no pain beyond days/weeks. For example, I was rear-ended and had my spine x-rayed. The x-rays showed nothing, but I have had back pain for years since the accident. Ditto for a concussion (MRI negative)--tension headaches for 2 years.
To clarify: having a court case that most likely doesn't end up in trial does not equate that I will lose. The vast majority of personal injury and property damage cases are settled. A good example is Dr Dao vs United Airlines. A lawsuit was filed for this highly publicized incident, but it was settled.
