The '80s pop icon said she'd received some comments about her skinny figure after performing a couple shows in Chile.
"I feel compelled to address a health-related issue I have been dealing with. Last year, I was diagnosed with Lyme disease. It is an elusive disease that disguises itself as many other things and creates a lot of pain and discomfort along the way," she wrote Wednesday on her website. "I am not exactly sure when or where I picked it up, but, in the early spring, I began to show unusual symptoms. A lot of Lyme symptoms mimic symptoms of anxiety and stress."
"The first symptoms came in the form of food sensitivities. I found I could not touch sugar, starch, caffeine, certain oils etc., without having a severe reaction that felt like jolts of electricity running through my body," she wrote.
"At times, my boyfriend would insist I eat some pasta and butter, even though I did not feel great doing it," she says. "'You need to gain weight,' he would say. My spine was frail and unprotected."
"I actually feel like me again," she said.
