He was scheduled to perform in New Orleans at last weekend’s Essence Festival but he couldn’t make it.

On Monday, he posted a video on Instagram. Dressed in a hospital gown, Alsina said, “I woke up one day and wasn’t able to walk. I couldn’t feel my legs. My doctor ended up admitting me into the hospital. They’re doing a bunch of tests.”

He continued, “[The doctor] said I have some nerve damage going on throughout my whole body that I have to go into a recovery process for. It’s like my immune system just went oN vacation. So, I’m just waiting on it to come on back so we can get together and do what it do.”
