But one night during pre-season, I woke up and just couldn't move my legs. I started to panic a bit and ended up having to go to hospital. They couldn't diagnose what it was.
"After five days of not being able to put one foot in front of the other, I knew there was definitely something wrong."
'It could have been fatal'
White explains doctors eventually told him that it was a blood infection in his leg that had turned his world upside down.
"It was really quite serious and had it gone on any longer it could've been fatal," he told BBC Scotland.
"The doctors emphasised to my family how serious it was and for them it was really hard, but if it wasn't for them I don't know if I would've got through it.
"I felt crippled. I couldn't physically move or do anything that my body was telling me to do, and when I finally did get to walk, it was a struggle.
"I was put on antibiotics and I thought I would maybe only be out for a month or two, but there was poison that formed around the infection which meant they had to operate on me and that delayed my comeback by about three or four months."
