"Watching at home is never easy when you've worked all summer and feel like you've kind of changed yourself a little bit to have a lot of success this season, and then have that false start to begin with, it's tough to deal with mentally."
Backes missed the first five games as he recovered from the illness, but returned to the ice on Tuesday morning for practice at Warrior Ice Arena and is hoping to be back in the lineup on Thursday against Vancouver.
"I think coming back and having the extra energy today…the past is the past, and we have to look at what the next step is to try to be the best player I can be to help us win games, and that's what the focus is," said Backes.
"Progress certainly. Return, we'll see. And long-term prognosis, we'll have to discuss with the really smart [medical] guys."
With the team on the road for nearly a week, Backes, who was unable to partake in any physical activity for six or seven days, worked with the team's medical staff and skating coach to get back into shape.
"Being able to skate with the guys, I was like a kid at the candy store before practice," said Backes, who lost nearly 10 pounds through the ordeal. "For me personally, felt good out there. It's nice to be back on the ice and smiling most of the day, just knowing that hopefully I'll be playing ice hockey in the future"
Backes, who still is not quite sure what spurred the illness, sought advice from former Patriots offensive lineman Matt Light, who battled Crohn's disease, another intestinal problem, later in his career.
"Got his insight on professional athletes and dealing with these kinds of issues," said Backes. "Trying to information gather and being as smart as I can so that I can be available as often as possible and be as productive as possible when I am available."
Bruins head coach Bruce Cassidy said Backes is a possibility to return to the lineup this week.
"He skated a little when we were away…we'll consult with the medical staff going forward, his plan," said Cassidy. "Potentially [will] be an option Thursday. That should sort itself out over the next few days."
