After Lewis Hamilton finished third at the Hungarian Grand Prix, attention turned to his continuing battle to stay race ready with an ongoing health issue.
The British driver appeared unsteady on his feet on the podium in Budapest, and required assistance onto the podium.
He spoke to the Mercedes team doctor, and elaborated on his condition after the race.
"I haven’t spoken to anyone about Long Covid but I think it is lingering there," Hamilton said after the race.
"I remember the effects of when I had it and training has been different since then. The level of fatigue that you get is different and it is a real challenge.
"I am trying to keep training and preparing as best I can. Who knows what it is today? Maybe hydration. I don’t know but it was definitely different."
Hamilton continued to explain that he had been suffering with a similar issue at Silverstone, but that the symptoms today were 'way worse.'
"I was having real dizziness and everything got a bit blurry on the podium,’ Hamilton explained.
"I have been fighting all year with staying healthy and what happened at the end of last year but still it is a battle."
