Intersection Syndrome is a painful condition that affects the thumb side of the forarm where two muscles cross over, or intersect, two underlying wrist tendons.

Intersection Syndrome is often confused with another condition called DeQuervain's Syndrome, which is an irritation of the upper set of tendons at the wrist.
