The 29-year-old England international, who is expected to be England's first-choice number seven for the end-of-season World Cup, underwent emergency surgery to remove his appendix just 13 days ago but is poised to play against St Helens in Thursday's first play-off semi-final.
"I'm taking each day as it comes," he said after being named in the Super League Dream Team for the third successive year after a record-breaking season with the table-toppers. "I keep pushing it day by day and it's progressing slowly but surely.
"I'll have a late fitness test on Wednesday and hopefully get the green light."
After a first diagnosis in hospital, Gale was told both his Grand Final hopes and his World Cup dream were at an end, although he was initially treated for indigestion.
"I rang my physiotherapist on the Monday and, when I told what sort of pain it was, he prescribed Gaviscon," Gale said. "He won't thank me for that.
"The pain was pretty tough and it got gradually worse. He rang 111 for me and they came and hooked me up to a drip. The doctor said straight away 'you'll have to have an operation tonight'.
"It was a bit of a shock to be honest. I thought it might have been a bit of food poisoning, I didn't have a clue. I felt a bit sick and I put it down to a gym session.
"After pressing on my stomach, she said 'look, your season is over, you won't be going to Australia'.
"Then someone else then came in and assured me it wasn't that bad but for two hours I laid on the bed and thought 'everything I've done this year has all come to and end and it was quite hard to take."
Gale, who had keyhole surgery, will take encouragement from the experience of Hull forward Chris Green, who made his return from an appendectomy against Castleford last Friday, just three weeks on from his operation.
"The doctors said three weeks but we in rugby league we tend not to listen to doctors," Gale added. "It all went well and I'm feeling fit and healthy again.
"It will be two weeks and two days which is a bit sooner than Chris Green, but we're all different individuals, it's not set in stone."
Castleford coach Daryl Powell intends to include Gale in the 19-man squad he names on Tuesday but will not make a final decision for another 24 hours.
"He's had a run today," Powell said. "He hasn't had any contact so we'll wait until Wednesday and make a decision after seeing how he comes through the final session. He'll be close I think."
St Helens coach Justin Holbrook, who says Jonny Lomax will be be fit to return to stand-off after missing the win at Salford Red Devils with a slight calf strain, expects Gale to play.
"I think he should play and I hope he does," Holbrook said. "He's had a great season and he deserves to play in a semi-final."
