Speaking on the Rio Ferdinand Presents podcast, the Red Devils icon said: "I had a mad virus. I thought lights were out at some point, I thought it was gonna happen. I thought I was minutes away from lights out, seriously. I was in my house, I was in my bed like this [pained expression] and I couldn't even open my eyes. Then, the headache I had… I don't get migraines or nothing else so I don't know what they're like. I thought my head was in a vice and my eyes were going to pop out.
"Then, I was being sick, projectile vomiting in the toilet, I got back to bed and I was having vertigo. I was holding onto the sheets, I didn't know where I was. It was crazy."
He added: "I had to go to hospital and the doctor even said to me, 'Do you want an ambulance'? So that's when I knew. He went, 'We're going to get your brain scanned'. I thought it was a virus or a flu or something so when he mentioned brain scan and the ambulance, the panic was nuts. I went to hospital and I was in there for a few days. I couldn't even enjoy the hospital food. The soup and the ice cream normally does wonders."
