1 Injuring a nerve (a neck injury may cause you to feel numbness anywhere along your arm or hand, while a low back injury can cause numbness or tingling down the back of your leg). 2  Pressure on the nerves of the spine, such as from a herniated disk.
Broil the steak for 8 to 12 minutes, turning once. Put the broiler pan on the top rack of the oven and cook the steak four to six minutes on each side. A London broil that goes for 8 minutes will cook to rare, while a steak that cooks for 10 minutes will cook to medium-rare to rare. For a medium-well steak, a full 12 minutes may be necessary. Broiling the steak for too much longer will likely dry it out, however.
Roast a London broil roast in 350 degree oven for 30 to 35 minutes per pound for a rare roast. Add an additional 5 to 10 minutes per pound for a roast that is more well done. If grilling or broiling a small London broil roast, plan on cooking for 5 to 10 minutes per side and then cooking over cooler coals for another 10 minutes or until the internal temperature reaches at least 145 degrees.
