If you are injured in an accident, act accordingly. Seek treatment right away. Waiting to receive treatment can hurt your claim.
Some medical providers, known as Third-Party Liability providers, will not charge you up front. Others will. Know the difference.
If your treatment takes place over a period of time, treat CONTINUOUSLY. Do not stop treatment until your doctor releases you. Gaps in treatment can hurt your claim.
Document who and where you treat with. Request records from everywhere you go related to your treatment.
Be wary of overtreating – your treatment should fit your injuries, and your injuries should fit the accident. Treating for something too severe (i.e. severe back problems after a small fender bender) can hurt your claim.
