Did Jesus go to the pagan temples of the Greeks and Romans to heal people?

There is no mention of Jesus going to such temples. In the gospels, he restricts his travels to with the borders of Israel and Judea. Neither nation had any "Greek or Roman" temples as they were dominated by the Jewish religion. So there would have been few if any such temples for Jesus to have entered.

The closet we have to this is in the gospel of John were a group of Greeks attending on of the feast in Jerusalem ask one of the disciplines to arrange a special interview (teaching session) with Jesus. Jesus' response was to told his disciples to tell hem that "unless a kernal of corn falls into the ground and dies, it will not produce fruit". Meaning that he would not come to them on their terms. They had to leave their pagan religion behind (die to it) and come over to his religion if they wanted to get anything from him.

Jesus came for the Jews of his time and never went into what would have been considered 'unclean' places, such as temples to 'false gods'. BTW, those temples can't technically be considered pagan because that would did not really exist then. They would have been 'Gentile' temples.

no, he probaly didn't even exist
