10yo - says elbows need oiling

[BlueChampagne]

Over the last couple of weeks, DS2 has started what seems like a tic of stretching his arms out a lot, rather as if he's rowing. He says he feels his elbows need oiling. Is this just a tic or might there be more to it?

Is his elbow sore? Does it need to "click" to provide some pain relief?

No, just stretch them. However yesterday, when I started asking more questions, he said they had stopped bothering him, so perhaps we just put it down to growing.
