Melanie “Mel B” Brownis speaking out about her health scare.

Brown, 43, went to the hospital on Friday,complaining of being blinded in her right eye. A rep for the Spice Girls told PEOPLE that the singer was diagnosed with iritis and uveitis, a form of eye inflammation.

In a TuesdayInstagram post, Brown thanked her followers for their support and explained her diagnosis.

“Thank you so much for all the lovely support and messages I’ve had about my eye,” she began. “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.”

Brown then turned to her fans to ask for help finding a “very cool” eye patch suitable for Scary Spice.

“I’m still dealing with it and will be [for] the next 3/4 months to fully get it under control but I’m no longer worried that my condition will get worse,” she wrote. “My only problem now is I have to find a very cool Scary eye patch. Does anyone — apart fromMadonna— know where I can get one?”

After being treated, the singer returned to rehearsals for theupcoming Spice Girls tour,The Sunreports.

A source close to Browntold PEOPLEthatrehearsals for the tour, which kicks off on Friday, are going smoothly.

“They just had the friends and family show and it went well; her youngest daughter came out. She’s very involved with the tour and she’s excited about it. All is going well,” the insider said.

On Sunday, while preparing for the “dress run” of their show, Brown posted a glamorous behind-the-scenes clip of her bedazzled animal-print nails.

“Getting glam ready for “spice girls” dress run yipppeeee,” she wrote.

Tagging her fellow bandmatesMelanie “Mel C” Chisholm,Geri Halliwell HornerandEmma Bunton, she added, “it’s show time.”

The four women, who are hitting the road without fellow bandmateVictoria Beckham, have put on a united front throughout the rehearsal process despite a little drama.

Shortly after Brown claimed that she and Halliwell Hornerslept togetherback in the day — claims which Halliwell Horner went on to deny — the pair seemed to put the incident behind them.
