The 25-year-old has joined Walsall on loan having made just four appearances for the Potters since a £1.2million move from Southampton two years ago.
"When I came from Southampton I was injured and I didn't really get the support I would have liked," Davies told the Express and Star.
"I felt I was being punished in my second season for not being fit in the first year.
"He (Pulis) actually signed me when I was injured and then when I got to the club I wasn't in his plans straight away, so it was hard.
"I had a knee injury which is now absolutely fine and I just needed support - which I didn't get.
"I was getting sick of sitting around at Stoke just knowing what I can do on a football pitch.
"Having to train with the young kids, I was thinking: 'I've got to get myself out there again, start playing football and just enjoying myself' because at Stoke I wasn't doing that at all."
