A dad was left needing surgery after hearing a 'pop' at the gym while lifting weights.
Barry Rowlands said he 'thought nothing of it at the time' when he heard the noise and felt a bit of pain in his left shoulder.
But the 38-year-old said he then woke up in agony, and couldn't move his arm at all, the Liverpool Echo reports.
He later a scan which revealed his tendons had come off his shoulder bone, an injury which would need surgery to fix.

Dad-of-three Barry, from New Ferry in the Wirral, didn't want to be put to sleep for the operation so was awake for the entire five-hour procedure.
Speaking of the day he injured his arm, he said: "I heard like a popping sound but thought nothing of it at the time.

"The next day I couldn't move my arm it was absolutely killing me with pain."
Barry added: "The thought of being put to sleep, I don't know, it just scared me, so I asked if I could be awake for the operation.
"My surgeon said he had never done that before, but he agreed, so I was awake for the whole five hour surgery."
Barry had taken his iPad in with him to occupy himself while the medical team reattached his tendons and added anchors to his shoulder, but he didn't use it.

He said: "I just watched the full surgery - it was fascinating, I loved it - I would recommend it.
"The team was great, the anaesthetist kept me calm through the procedure and I chatted to my surgeon about what he was doing."
Barry admitted he is not the type to hide behind the cushions when a medical scene comes on TV and said if his arm doesn't improve by January, he is fully prepared to go through the operation awake again.
He said: "My kids think I am a bit mad going through it awake, but I was not phased by it at all.
"I can use my arm now, there is a little bit of pain still and I am still having physio, but, as my doctors keep telling me, it will take time to heal.
"There was no warning this was going to happen and it is not very common.
"But my girlfriend, Emma McCromick and my mum and dad have been amazing helping my recovery."
