"I'm now receiving professional help to manage my medications and the ways that I deal with back pain and a sleep disorder", he said in the post Monday night, a day after the U.S. Open that drew low television ratings in part because of his absence.
Tiger Woods released a statement on Twitter announcing that he is receiving "professional help" to deal with his pain medications, back pain, and sleep disorder. "I want to thank everyone for the fantastic outpouring of support", he wrote.
In the statement, Woods also thanked fans and players.
Tiger Woods is getting some help.
Woods, 41, has only played twice this year - missing one cut and withdrawing once.
His comeback lasted three tournaments before he was sidelined again with back problems, prompting the fourth surgery.
At the time, Woods issued a statement that alcohol was not involved, a claim substantiated by breathalyzer test results released by police. He told officers he was taking a combination of painkilling medication, including the opioid Vicodin, as well an anxiety medication, Xanax.
Woods, 41, is scheduled to be arraigned on the DUI charge on August 9.
Woods apologized May 29 saying he had an "unexpected reaction" to medications. He raced to 14 major wins, last capturing the U.S. Open in 2008.
Back problems have limited Woods to just 19 tournaments since 2014.
Whether he will do that now is unclear.
