Lohse to have surgery today on right arm

SAN DIEGO -- St. Louis Cardinals right-hander Kyle Lohse will undergo surgery on his right forearm today.

Lohse, who was placed on the 15-day disabled list Thursday with exertional compartment syndrome, will have the surgery performed by Dr. Stephen Shin in Los Angeles.

Lohse was examined by Shin on Wednesday in Los Angeles.

"It explains everything I've been feeling throughout the last year," Lohse said. "It explains why it's such a hard thing to diagnose."

Exertional compartment syndrome is an uncommon, exercise-induced neuromuscular condition that causes pain and swelling in legs or arms and can be difficult to identify.

Lohse will have fascial release surgery performed on his forearm. There is no timetable for his return.

Lohse, who is 1-4 with a 5.89 ERA, has not pitched since Saturday, when he lasted only 3 1/3 innings in a 10-7 loss at the Los Angeles Angels. Lohse said he experienced fatigue and cramping in his forearm in that start, similar to what he's been feeling since last season.
