The 25-year-old was taken off having scored a try in the Munstermen's 31-7 GUINNESS PRO12 victory over Zebre in Italy, and missed his side's European clashes with Saracens and Sale Sharks.
But with Ireland's clash with Italy looming this weekend, Murray has declared himself fully fit and admits he was frustrated to miss out on any action with Munster.
"I got injured against Zebre with Munster in the GUINNESS PRO12 about four weeks ago now and just over extended my neck so it required a couple of weeks out," he said.
"It was probably a bit too soon to play in those two European games for Munster last month. I was probably a bit touch and go.
"I maybe could have got back and played, but speaking to specialists and doctors and all that, they advised against it.
"It was a disc problem in my neck but it's gone now. There's no hassle over it. I just ran into a player's chest and squashed myself. It wasn't the smartest idea. I won't be doing that again!
"It's tough. Rehab is annoying as you can't train fully. You can't get your full weights programme in. You can't be out on the pitch with the lads. It is just part and parcel of professional sport.
"But I rehabbed it well. Did a bit of contact on Friday with Ireland and did a bit more yesterday and came through really well and I'm feeling good and fit to play - I've gotten through that first contact fear, if you want to call it that."
