The only thing that wakes me in the night, CKLD, is my ever-weakening bladder! The tingling may happen whilst I sleep but it doesn't wake me - I have, however, been woken several times lately by pins and needles in my hand which I think comes from me lying on it. I tend to lie on one side or the other and almost always fall asleep lying with my head on my hand or arm. I wonder if it might stop once my current period is over, and therefore be hormonal as you suggest. I guess I have to wait and see.
Jaypo, I'm not aware of having hurt my neck but I suppose nerve damage somewhere might be the culprit.
I've been worrying that it might be connected to a brain tumour or the such, I do have health anxiety.
