The Owls attacker says he is "very disappointed" with the Football Association who suspended him for three matches following a probe into events at Mansfield Town in July.
Forestieri, who was also given a Â£25,000 fine when he was found guilty of violent conduct, claims it was Stags opponents who instigated the trouble at the end of a 2-1 Wednesday defeat at Field Mill.
"I was very disappointed in this situation," said the Argentine who came on as a substitute in Sunday's 2-1 win at Bristol City which moved the Owls into a Championship play-off spot.
"The Mansfield players start kicking and they punch me in the face and the referee says nothing to them. I am punished and I am very disappointed.
"The FA can do anything they want, but their guy punches me first."
Forestieri, who missed Championship matches against Stoke City, Nottingham Forest and Aston Villa because of the ban, clearly took a blow to the head after the final whistle from a Mansfield player who escaped censure.Â
"TheÂ FA don't do nothing to him," he said. "For this, I am disappointed that I am fined and given three matches.
"I think if the FA has evidence that someone kicked me and punched me in the face, they need to do the same (punishment) for both sides, not just Sheffield Wednesday."
The Stags' Jacob Mellis was handed a three-match suspension and Â£1,500 fine for a separate incident involving Owls captain Tom Lees.
The FA have also been investigating a claim that Forestieri racially abused a Mansfield opponent, something he and the Owls vehemently refute. The game's governing body haven't isssued any charge so far.
"I think it is finished now," Forestieri said. "I need to focus on the Championship."
Victory at Ashton Gate, where two goals from Lucas Joao did the damage, lifted Wednesday's men into sixth spot heading into the international break. Jos Luhukay's side have now lost only one of their last nine league outings.
The away triumph followed home draws against pace-setters Leeds United and West Bromwich Albion, and Forestieri said: "We are very happy with the win. We work very hard.Â
"It was very disappointing at home, the draws with Leeds and West Brom, even though they were top of the league. We need to win.Â
"We come to Bristol and we know they are a difficult team to beat. I am so happy we win and so happy with Lucas's work, that he scored twice. We need to carry on like this."
