I think you've received some poor legal advice.
Michigan's auto accident threshold law changed on July 31, 2010. Although there may have been some argument under the previous and far harsher threshold law under Kreiner v. Fischer, based upon your description I clearly see that you have a legitimate claim. Temporal/durational factors were extremely important under the old law, and there were some unpublished opinions that did suggest you need to suffer an impairment of longer than a year, such as Gagne and others. However these temporal barriers were removed by McCormick.
You certainly have a legitimate claim under our current auto injury threshold law.

Who said that this wasn't a serious impairment? A serious impairment does not need to be permanent under the law. Dependent upon your pre-accident injury status, you may have a viable claim. Please call my office to discuss your case. (866) 288-6529
