1. Not going to the doctor or hospital So important after your accident, you need to be checked out by a physician to see what the extent of your injuries are and to make sure you start getting better. After your accident you should get seek medical attention as soon as possible. 2. Not following your doctor's instructions The doctors are the professionals. they are going to prescribe you medicine, physical therapy, instructions about staying off your feet, staying in bed. If you don't follow their instructions, It will take longer for you to recover, your case will take longer, and you could end up not getting as big a settlement because of that. The third mistake is trying to do too much too soon after your accident You may be in a lot of pain, but if you go around pretending like you're not hurt, you could do yourself more damage and also hurt your case. Someone who goes back to work the very next day after an accident is not going to have as large a settlement as someone who really takes the time they need to recover from their injuries A very similar mistake to that is downplaying your injuries That's right, often we have these guys that want to look tough and that they've got it all together and can't get hurt. Sometimes admitting to yourself that your injuries are seriuos and acting like it will not only help you heal quicker, but it can really help your case. Every case is different, so you really need to sit down with a lawyer to figure out what is the best way to go from there.
