Because the symptoms are random and vague (aside from a bull's-eye rash), Lyme disease can be hard to diagnose. Unfortunately, unless Lyme disease is treated promptly, it can also be difficult to cure. For these reasons, people living in high-risk areas should be knowledgeable about Lyme disease.
Scleroderma (pronounced SKLEER-oh-der-ma) is a disease that affects your skin. When you have scleroderma, your skin gradually tightens and thickens or hardens. It can’t stretch like it used to.

Lyme disease is caused by bacteria transmitted through the bite of the tiny black-legged, or deer, tick found in the Eastern and Central U.S. and the western black-legged tick in the Pacific West.

In humans, the bacteria may cause flu-like symptoms. It invades many tissues -- including the heart and nervous system -- and triggers an immune response that can lead to Lyme arthritis.
