Fair Go presenter Kevin Milne may have to have surgery on a benign tumour that is threatening his sight and other parts of his brain.
The 60-year-old was diagnosed with the tumour last week, after he became constantly tired and rundown .
"This thing is dreadful -- it slowly winds you down. All your muscles stop operating," he told the Herald on Sunday.
He said he noticed something was wrong in March, when his body started stiffening up.
"I had real difficulty getting out of a chair and out of a car; getting out of bed in the morning was the worst.
"I had terrible sleeplessness, I was feeling quite down -- it was like mild depression. I thought that was because I wasn't getting enough sleep. My hands were tingling."
Last week he admitted himself into hospital after he became short of breath during a walk with his wife Linda and his heart then started pumping "really hard".
Specialists later established it was a tumour in his pituitary gland.
He said the diagnosis of his condition was fantastic because he could now get back to a "situation that I had forgotten about".
Milne, who has been away from work for two weeks, has started hormone replacement therapy.
He underwent an MRI on Thursday and was now waiting to see whether surgery is required to protect his eyes and brain.
