Aerosmith frontman Steven Tyler says he checked into a rehab facility in search of a "safe environment" to recover from several foot surgeries and physical therapy.
Tyler says in a statement that the surgeries were to correct long-time foot injuries resulting from his physical performances as the singer for the blues-rock band. The 60-year-old singer was known for heavy drug and alcohol abuse in the 1970s and early 1980s.
But he completed rehabilitation in 1986, after which Aerosmith enjoyed a successful revival.
Tyler said doctors told him his feet would require "a few surgeries over time."
He described the pain after surgery as "intense" and "greater than I'd anticipated."
"The months of rehabilitative care and the painful strain of physical therapy were traumatic," Tyler's statement said. "I really needed a safe environment to recuperate where I could shut off my phone and get back on my feet."
