The “Cranes in the Sky” singer said that she has been receiving treatment for more than five months for the disorder affecting her autonomic nervous system, which regulates heart rate, blood pressure, digestion and body temperature. “Sometimes I feel cool, and other times not so cool at all,” Solange wrote, adding that the diagnosis is complicated. “I’m still learning so much myself, but right now, my doctors are not clearing me for such an extended lengthy flight, and doing a rigorous show right after.” The 31-year-old was scheduled to close out the AfroPunk Fest in Johannesburg on Sunday, the South African version of the Brooklyn-based festival that she headlined and curated in August. “I can’t thank AfroPunk enough for their support, and to all of the other festivals this past summer/fall who have known about my health, kept it confidential, and gone out of their way to make me feel supported while doing these shows,” she wrote. “As a part of the self care that I’ve tried to encourage this past year, it needs to start with myself, and I’m looking forward to doing a better job of this 2018.” By Glenn Gamboa email@example.com @ndmusic Glenn Gamboa is Newsday's music critic, covering entertainment news and events since 2000.
