Fortunately for me, my wife is an attorney who sometimes handles personal injury and medical malpractice cases. Although we have settled the property damage part of my claim, there is still the injury aspect to deal with. You want to wait at least 6-months after the accident before seeking to recover the injury portion of your claim in case some latent medical issues develop. Make sure you go to the doctor to seek medical attention for any injuries that you suffered; not only because that's a wise thing to do, but also to document the extent of the injuries and treatment you received.
For obvious reasons, I don't agree with all of the negative attorney comments made in earlier posts. I would not recommend that you try to go it alone you if you are seeking to recover damages for medical expenses and pain and suffering from the insurance company. You will never come close to what a reputable attorney will recover for you even after the attorney fees, expenses, and insurance reimbursement are paid. A property damaged claim is one thing, but an injury claim is quite another matter. Stay away from the personal injury attorneys that advertise a lot. They deal in volume and are only interested in settling your claim as quickly as possible, so they are not going to seek to maximize your settlement amount.
A typical law firm will retain about 35% of the settlement as their fee. Expenses in your case should be fairly minimal and include things like cost of obtaining medical records, copying, postage, etc. You may also be required to reimburse the insurance company for their expenses, but that is usually negotiable and depends on state statutes, policy caps, etc.
At any rate, you will still come out ahead versus trying trying to negotiate on your own. Remember though, no matter how you slice you will never be made completely whole. The system just doesn't work that way.
PS - Jamie, how many miles where on your bike at the time of the accident?
