Mike Woodson said Amar’e Stoudemire will be out “a while’’ because of knee swelling. Stoudemire denied the assertion and tweeted he’s not even injured and his “knees feel great.’’

The Knicks are such a certifiable mess nobody can agree on anything. It is clear Stoudemire and the Knicks medical staff have conflicting agendas.

The day after a gut-wrenching home loss to the Wizards, Woodson revealed unsolicited Tuesday and at the end of his post-practice press conference Stoudemire “is going to be out awhile, he won’t play tomorrow.’’ Woodson began to walk away when The Post asked what was wrong and the Knicks coach said Stoudemire’s “knee swelled a little bit.’’

According to a source, Stoudemire was angered there was speculation about a future surgery and unleashed a defiant tweet to claim he doesn’t consider himself injured.
