"If you manage to walk with your son again in the garden, be satisfied, they told me", Cazorla said in an interview with Spanish publication Marca.
Cazorla first suffered a blow to his ankle while on global duty with Spain back in 2013 and, having missed six months of the previous season following surgery to correct a ruptured knee ligament, underwent another operation last December.
He was also told by doctors that he may never walk again.
A skin graft from his left arm was required to cover the wound, meaning part of a tattoo is now on his foot.
He shared a photograph of the state of his right ankle following the effects of the numerous operations and it appeared on Marca's front page.
His eighth and last surgery was carried out in May in Spain with Vitoria-based doctor Mikel Sanchez horrified by what he discovered.
The severity of Cazorla's injury sparked fears that he could be forced into an early retirement, although earlier this year Arsenal, in a show of faith, exercised their option to extend his expiring contract by a further 12 months to June 2018.
"Everything that I have gone through has not been as simple an injury as people have believed", added Cazorla.
"The problem was that it did not heal and the wounds would reopen, become infected".
The Spaniard signed for the club in 2012 and has scored 25 Premier League goals in over 100 appearances. Although Cazorla's family are still living in London where his children are at school, he has been based at a hotel in Salamanca since July, where he is working daily with Juan Carlos Herraez, the Spain team's physiotherapist. Picking up an infection, Cazorla continued with his football comeback, but things got worse, and then came the shock. "Nobody trusted me but I do, I still do, although the pain keeps me cautious". "Now I realise who is who [those who care]".
"Almost every day I receive a message from Iniesta, Silva and Villa".
