BLACK LABEL SOCIETY last week dropped off the remaining dates on the "Pedal To The Metal Tour" due to frontman Zakk Wylde's health problems.In a September 1 posting on his Twitter page, Wylde offers the following update on his condition: "I spent three days in a hospital in Eugene, Oregon where they gave me a 24-hour drip of Heparin [an anticoagulant which is used to decrease the clotting ability of the blood and help prevent harmful clots from forming in the blood vessels — Ed.] where they could monitor me. The next two days I received shots of Heparin into my stomach. Each shot lasted 24 hours. I was given a CT scan where they found three clots. I was then told each one of the clots passed through my heart. "I just received an ultrasound. My left leg has a clot above the side and behind my knee, my calf and running into my heel. My right leg has a clot in between my calf and ankle. "In a couple of days, I'll have another CT scan to see how my lungs are doing. "On the brighter side of BLACK LABEL, they shaved off four inches from my love cannon, so Barbaranne [Zakk's wife] won't be in such excruciating pain as I hammer and plough my love into her Thor-style! Aside of that, all is peachy keen!" Wylde stated in a recent Twitter message that he is unable to sing at the moment "because pushing can cause an embolism." An embolism occurs when an object migrates from one part of the body (through circulation) and causes a blockage (occlusion) of a blood vessel in another part of the body. The "Pedal To The Metal Tour" will continue without BLACK LABEL SOCIETY, and the rest of the bands — MUDVAYNE, STATIC-X, SUICIDE SILENCE and BURY YOUR DEAD — will carry on with the trek as scheduled. Further updates on Zakk's medical condition will become available as they are known.
