Olson told INSIDE EDITION that Sheen sweated all the time, even though he claims he was diagnosed after their split.
Bree Olson says when she lived with her ex Charlie Sheen, he had physical symptoms that she now believes were signs of HIV.
The former porn star is back talking to INSIDE EDITION after the actor's rep denounced her previous interview.
"He and his managers want to treat me like I was just another 'unsavory woman,'" she said.

Olson says she believes Sheen was diagnosed with HIV when they were living together in 2011. But Sheen, who revealed his diagnosis in an interview on the Today show on Tuesday, says he did not find out until after their relationship ended.
"It would give me peace of mind for Charlie to say a date [he found out]," Olson told INSIDE EDITION on Wednesday. "That interview was so wishy-washy."
INSIDE EDITION's Megan Alexander asked her: "Charlie said that some of the symptoms of HIV were that he had headaches, massive headaches and breaking out in sweats all the time. Did you observe that?"
Olson responded: "Yes! Sweating all the time. He would keep the house in ridiculously cold temperatures."
While Olson is livid over his announcement, another of his exes, Natalie Kenly, is defending him.

"He is not a monster," Kenly told People magazine. "He's a good man and I feel very fortunate to have spent the time with him that I did. I'm so sad to hear of his health troubles."
Olson was surprised by the reaction.
"We should be together on this, like, 'Charlie, why didn't you tell?'" she told INSIDE EDITION. "That's all I want - for him to be a decent human being and to have let us know that this was going on."
