The Real Housewives of Beverly Hills star Teddi Mellencamp was admitted to the hospital due to “unbearable” pain after suffering from “severe and debilitating” headaches.

After the doctor’s visit, the TV personality,

who participated in the reality show for three seasons,

disclosed that they found she had several brain tumors.

“I had to be admitted to the hospital yesterday due to the excruciating pain,”

Mellencamp posted on her Instagram page on Wednesday.

“My brain has several tumors that the doctors believe have been growing for at least six months, according to the results of an MRI and CT scan.”

On February 12, she told her followers that two of the tumors would be surgically removed.

Radiation therapy will “be dealt with via a later date” for the remaining, smaller tumors.
