Paul “H.R.” Hudson, lead singer for legendary punk outfit Bad Brains, has announced he will undergo brain surgery later this month on February 21. The musician revealed the news to Loudwire (via Rolling Stone) during a recent interview.

Last March, it was revealed that H.R. was suffering from a rare neurobiological disorder known as SUNCT, which stands for short-lasting unilateral neuralgiform headache with conjunctival injection and causes Hudson to suffer from extreme cluster headaches throughout the day and night. The singer’s wife started a GoFundMe page to raise money for his medical costs. On the page, she wrote about her husbands affliction, saying, “The intensity of the nighttime headaches is so great that he yells, cries out, groans, and sobs — repeatedly, every few minutes, for most of the night. He can’t work. He has no quality of life.”

Now, H.R. tells Loudwire that he has qualified for the surgery after attempting to treat and manage the syndrome with pharmaceuticals and holistic methods, with some success. The singer is reportedly calm regarding the procedure, noting that his doctor has performed the same surgery over 200 times.
