Pedroia said he has three options -- surgery, resting for the remainder of the season or to continue playing -- and indicated that a decision may come soon.
On Wednesday, manager John Farrell said there was no final decision but the team was leaning toward surgery.
"Nothing definitive. He and we are still gathering information," Farrell said Wednesday. "It's moving towards probably a procedure but nothing definitive is scheduled right now."
If surgery is the path he takes, Pedroia said he would have it immediately. The operation would be minor and Pedroia said he would expect to go through a normal offseason.
"They're talking. There's some options that they're going over," Pedroia said. "We're trying to do the best we can to figure out a plan and go forward."
Pedroia said he's been playing through the injury most of the season. Farrell said that an MRI conducted Tuesday showed further inflammation in the area, prompting the need for the team to discuss their options.
Pedroia said he started dealing with the issue during the home opener against the Milwaukee Brewers, when he landed badly on his left wrist when upended on a double play relay. At the time, Pedroia was still rehabbing from offseason thumb surgery that was delayed until November as a result of the Red Sox's World Series run.
"We've tried to manage it the best we can," Pedroia said. "It just gets to a point where obviously it hurts so it's tough going out there and trying to do what you're accustomed to doing and you can't.
It has been a disappointing season at the plate for Pedroia, who is hitting .278 with seven home runs, 53 RBIs and six stolen bases -- far lower than his typical season averages.
He finished the 2013 season hitting .301 with nine homers, 84 RBIs and 17 stolen bases.
"That's a lot of it. You don't have your hand strength, you're not able to follow through like you normally do," Pedroia said. "It makes it tough, but you've got to try to find ways in other areas to help your team win."
Before missing five games with a concussion earlier this month, Pedroia had played in all but four of the team's first 135 games this season.
"With Dustin it gets to the point of taking the decision out of his hands because he does want to continue to play. It hasn't been determined if he were to continue to play, does it put him at further risk," Farrell said. "I don't think the medical staff is saying that he's at further risk. It's just to the point where the discomfort is there."
Even with his options in front of him, Pedroia still showed reluctance toward shutting things down for the remainder of the season.
"Yeah, it's tough," he said. "You want to be out there playing. Obviously I love playing baseball and I love being out there with my teammates so it's tough."
In Pedroia's absence, Farrell said Brock Holt likely would play most of the reps at second. However, with Holt being shelved since Friday while battling an illness and a stiff neck that has been giving him headaches, recently acquired infielder Jemile Weeks played second on Tuesday.
Farrell said that Holt may return to the lineup over the weekend in Kansas City.
"While he feels better today, he's not ready to resume baseball activity. We're hopeful that would be in the coming days," Farrell said. "If he makes the progress that he did today coming in, we're hopeful that he'd be on the field in game this weekend."
Rookie outfielder Mookie Betts, a second baseman by trade, likely will remain in the outfield as Farrell said the team will be careful moving him back and forth between positions.
If surgery were to be performed, it would be the third successive year in which Pedroia will have had surgery for a hand injury. In addition to repairing his ulnar collateral ligament last November, Pedroia had a pin inserted into his right pinkie finger in October 2012.
"[My hands are] the most important part of my game, that's the tough part," Pedroia said. "It's one little thing here and there that can affect you. We'll get through it and I'll be better for it. I've learned a lot."
On July 23, a talent evaluator for another major league club told ESPN Boston he thought Pedroia had been playing hurt.
"Just like last year, something must be physically wrong," the evaluator said. "He'll never admit it, nor will the team. [But] the statistical drop-off is too drastic to ignore, given his history."
Pedroia, when told of those remarks, hinted at their accuracy at the time. Asked how much better he would be playing if his left hand were healthy, he said, "I'll be OK. It's part of playing, being an everyday player. I didn't say anything last season because I was playing every day."
Tuesday night, the same evaluator said, "He's a tough SOB. He needs to get that thing right. The curse of being so competitive.''
Last season, Pedroia and the Red Sox agreed on a seven-year contract extension that will keep the 31-year-old in Boston through 2021. With the Red Sox 21½ games out of first place entering Tuesday night and three games away from postseason elimination, the plan with Pedroia figures to err on the side of caution.
"His health is the most important," Farrell said. "That's all being reviewed right now. If it's determined that anything more severe can come out of that by playing, we'll certainly factor that in and not put him at further risk."
