I did a little research on lymes a couple of years ago. According to the health dept. it is assumed that there are way more cases than what is reported. Many Drs. are failing to run the tests neccesary to ascertain that a person has lymes. The reason behind this is some people do not exhibit all the symptoms, and the ones the do show just aren't severe enough to run up a red flag to the Dr. While some people show all of the symptoms, other people only show a portion of the signs and they aren't bad enough to indicate the disease. Still, others are able to overcome the disease without ever seeing a Dr.
