Yes, a person who is not a fault and was rear-ended by a huge soft drink trunk to the point that it drove into the trunk and back seat of a mid-size car should be compensated for pain and suffering....
A 'personal injury' or 'medical malpractice' specialist might be a good place to start.
The most common example of compensation for pain and suffering is a cash payout.
Your doctor and someone who works in an office and pushes pencils.
It depends on what kind of pain you are suffering from, try to find a medication that works for that type of pain
