Q. Can I recover if I have a "pre-existing condition"?

Yes. The fact that you have a "pre-existing condition" will not prohibit you from recovering from the "at-fault" driver. Your "pre-existing condition" is merely a factor to be considered in resolving your claim. The question is whether the "at-fault" driver aggravated your "pre-existing condition". The "at-fault" driver takes you in whatever condition you are at the time of the accident. The fact that someone else would not have been injured is irrelevant. A person in a weakened condition may actually recover more than an extremely fit person would recover in the same accident.
