Antonio Brown is now breaking his silence on his frost-damaged feet … told media members at Raiders camp that the blows make it difficult for him to play football .
"It's been a process with your feet," Brown said … "At any time you have many blisters, it's difficult to change direction, cut and run and be able to do what I do naturally."
Brown has been battling frost damage since he suffered a mishap in a cryotherapy room … but he has remained silent on the matter until he returned to Raiders camp in Napa, California on Tuesday.  Brown would not say exactly how the freak damage occurred – only revealing the whole thing has sucked – but he said he thinks he will be closer to returning to the field.
Remember when Olympic sprinter Justin Gatlin joined the guys on "TMZ Sports" (this week's night at FS1) … he said that when he suffered a similar injury it took him MONTHS to get back to full health.
But AB seems to be a little confident that he will be ready soon … says he has worked with a foot specialist to get closer to 100 percent.
By the way, Brown addressed his entire helmet drama … and said that he is working with the NFL to try to get him the Schutt he prefers.
"They have to certify it and do all the procedures," Brown said. "But we work with the NFL to make sure we follow all the procedures and are out there in the right equipment."
