Days after upsetting fans with a cryptic post where he referenced dying, Richard Simmons is opening up about being diagnosed with skin cancer.

The fitness guru sounded upbeat as he wrote about how a small skin issue led to a major health scare in a pair of lengthy Facebook posts on Tuesday.

Mirror mirror on the wall whats that blemish which is so small? Simmons, 75, began.

After noticing a strange looking bump under his right eye, the Sweatin to the Oldies star said he nursed his lesion with a tube of Neosporin which I would put on in the morning and the evening.

When he realized the over-the-counter treatment wasnt working, Simmons said he knew it was time to call my dermatologist.

At the appointment, his doctor took a skin sample and determined Simmons had cancer.
