Connie Hanafy had a passion for riding dirt bikes. Then, minor leg surgery sidelined the Deptford mother of two with crippling pain.

In the recovery room, Hanafy feels a tingling in her leg.

“Most patients will report at least a 50 percent reduction in pain,” Dr. Youssef Josephson, a pain specialist, said.
