Hollywood , California ( CNN ) -- Dr. Paul Nassif could n't tell if his friend Charlie Sheen was drunk last Thursday when the actor made the phone call that eventually led to a hospital visit and the latest controversy about Sheen 's rehab . `` I just was waking up , I was still very , very groggy and the phone rang and it was Charlie Sheen 's residence , '' Nassif told CNN Tuesday . `` I spoke to Charlie for a few minutes and he said he was in a lot of pain , and remember I 'm Charlie 's friend . I 'm not his doctor . I 'm a facial plastic surgeon . `` When I spoke to Charlie it sounded like he was in a lot of pain , severe pain , so when someone 's in severe pain you know it 's not like I 'm going to walk out my door and go see him . Plus I do n't even live that close next to him , '' Nassif said . `` When I usually hear something like that -- you do n't know what 's going on -- so the thing you always are going to do is dial 911 . `` I instructed the person I was speaking with to call 911 and then I also followed up to make sure that it was performed and kind of communicated somewhat to the paramedics , '' Nassif said . Porn actress Kacey Jordan has told media outlets that a two-day party preceded Sheen 's collapse in his Los Angeles home . Sheen has since entered rehab , and his hit sitcom `` Two and a Half Men '' has suspended production . Nassif could n't determine whether Sheen was drunk or high . `` I could n't tell if he was inebriated . I only spoke to him for a very brief moment because as soon as I heard him say he 's in a lot of pain I wanted to get on the phone with the assistant so they can just immediately dial 911 , '' Nassif said . Sheen and now ex-wife Brooke Mueller were married in Nassif 's Beverly Hills home , Nassif said . Nassif 's wife , Adrienne Maloof-Nassif , appears on `` Real Housewives of Beverly Hills . '' `` They wanted to get married , and a mutual friend introduced all of us , and they said , 'Let 's get married , can we get married at your house ? ' and that 's how we met and soon after that we became very good friends , '' Nassif said . Nassif drove Sheen home from the hospital , but he declined to provide details of their conversation . `` There were things he said I do n't feel comfortable '' disclosing , Nassif said . At another point in the interview , Nassif added : `` Obviously we all want Charlie to keep his sobriety . No one can push him into it . '' Sheen 's manager has said the actor is undergoing rehab at home , not in a residential facility . `` Where you do it does n't matter if you have someone with you that 's helping you , '' Nassif said . `` That would be nice to be at your own environment as long as you have the right structure .
