Sergio Perez left hospital on Monday, two nights after his horror Monaco crash.
The Mexican rookie suffered concussion and a bruised thigh in a high speed qualifying crash against the notorious barrier at the end of the tunnel.
"I feel okay," said the 21-year-old Sauber driver. "I have little bit of pain in my leg and in my neck, but this comes from muscles and is nothing to worry about. On Sunday I still felt a bit dizzy but that is all."
Perez admits he can't remember key moments about the crash.
I am missing some memories about what happened after the first impact
"I remember how I started Q3 and I also remember some of the accident. For the time being I am missing some memories about what happened after the first impact and the rescue procedures," he said.
He said he is "pretty sure" he will be well enough to drive in canada in two weeks.
Asked what he will be doing in the coming days, Perez answered: "Pretty simple -- everything to make sure I can drive in Canada."
