Melanie "Mel B" Brown took to Instagram on Wednesday to reveal that her vision was temporarily impaired after she was diagnosed with two eye conditions. The singer and former talk show host responded to online rumors that her health woes were related to an STI-related infection.

Brown uploaded a black-and-white photo of her wearing an eye patch. She explained the severity of her troubles in the post's caption: "Just so you know the real truth. I had an awful experience last week when I went blind in my right eye and my left eye went blurry," she said.

Refuting claims made in recent reports, the Spice Girl singer continued, "Even though the stupid press said I’m ok and this has happened to me many times before, just to be clear I was NOT ok and this has NEVER EVER happened to me before, so who every is selling this story "a close reliable source" is full of BS and needs to get there [sic] silly facts right big time.'"

Explaining the exact cause of her vision impairment, Brown said, "I was diagnosed by and eye specialist with severe IRITIS in my right eye and UVEITIS in my left eye."

Despite the frightening encounter, Brown says it's all under control. "I’m taking multiple prescription heavy duty eye drops and other medication the Dr. gave me that I have to take every day to keep the inflammation under control," she said.

"Also I’m being so well looked after by Team Spice special thanks to our paramedics too!!im still dealing with it and will be fir the next 3/4 months to fully get it under control but I’m no longer worried that my condition will get worse. My only problem now is I have to find a very cool Scary eye patch," Brown continued.

The singer's latest health issues came months after she was hospitalized with two broken ribs and a severed hand in December.

Brown is preparing for the 13-date Spice World tour, which begins on Friday in Dublin.
