If you are injured because of someone else's negligence, you may have to resort to a personal injury lawsuit in order to obtain payment for the medical care you will need in the future and to compensate you for your pain and suffering. If your injury falls under the workers' compensation system, or if you are receiving Medicare or can be expected to receive Medicare, you may need to create a special kind of trust, called a Medicare Set-Aside, to reimburse the government for future medical expenses related to your injury.
