"Surgeon fixed my hand. Nothing broken, just carpal tunnel. Behind my Anthrax drumkit soon - 9/13 in San Bernardino."

Charlie is referring to the Battle of San Bernardino show that also features Iron Maiden, Megadeth, Testament, Sabaton and Overkill.

Anthrax are currently in Europe in support of their 'Worship Music' album, playing festivals with temporary replacement drummer Jon Dette, who also covered for dropped Slayer drummer Dave Lombardo, pulling double-duties as both bands toured Australia earlier this year.

About carpal tunnel syndrome
Carpal tunnel syndrome (CTS) causes paresthesia, pain, numbness, and other symptoms in the distribution of the median nerve due to its compression at the wrist in the carpal tunnel. Some of the predisposing factors that can cause carpal tunnel syndrome include repetitive motions in work and work with vibrating tools.

A review of available scientific data by the National Institute for Occupational Safety and Health (NIOSH) has indicated that job tasks that involve highly repetitive manual acts or specific wrist postures were associated with incidents of CTS, but no causation has been established.

A splint to keep the wrist straight, and surgical release of the transverse carpal ligament are among the generally accepted treatments.
