An injured person's first responsibility is to seek effective medical attention to recover as fully and promptly as possible.

If the injured person has responsibilities to his or her family, at work or school there is a vital interest in recovery at the earliest.

In most cases the at-fault party or its insurance company will not pay for medical expenses on an on-going basis. If the injured person has medical insurance that can help and it should be used depending on the facts.  If there is no health insurance and there is a need for continuing treatment, treatment will probably need to be obtained on a lien or credit basis pending closure of the claim.  If you are represented, your attorney can probably offer the names of some medical providers that are willing to treat you on a lien basis (most medical providers will not).  

It's important to always self-monitor treatment type, efficacy and cost.  Failure to monitor treatment can result in disproportionate medical costs that make it difficult for the injured person to obtain a fair net settlement after liquidation of medical costs.

An experienced attorney can help keep an eye on your medical treatment with a view to how it may affect your net settlement, keeping in mind that prompt full recovery is your primary goal.

If you are not represented keep in mind that the insurance company may have a very different view than you of what is an appropriate amount of medical treatment or reasonable total cost of treatment based on the injury you sustained and the nature of the accident you were involved in.
