The Wales fly-half ruptured his Achilles during the Scarlets' Heineken Cup defeat to Exeter Chiefs last December.
Priestland underwent corrective surgery as a result and missed the entire RBS 6 Nations.
It was initially feared that Priestland could be out of action for six months but he has been passed fit to return to action and could face Cardiff Blues on the weekend.
"I'd never wish to rupture my Achilles again, but it's been good for me," he said.
"It's been nice to have a rest and get the rest of my body feeling good as well.
"All in all, I'm feeling pretty good and I'm just looking forward to getting back playing rugby and enjoying it.
"I've passed all the tests with the physios and conditioners, so it's whenever the coaches pick me now.
"It's up to them. It's out of my hands now, I just want to come back and feel good with the way I play."
Simon Easterby's men are currently battling the Ospreys for a place in the RaboDirect PRO12 play-off places.
They trail their west Wales rivals only on points difference and have a more favourable run in than the reigning champions.
The Scarlets finish the regular season with home clashes against Cardiff Blues and Benetton Treviso and Priestland is determined to make a difference.
"I'd love to get into the play-offs with the Scarlets, because as a group we've been close the last couple of years and not quite got there," added the 2012 Grand Slammer.
"This year we have the potential and I think we are going to get there, I would love to be a part of it."
