Brilliant. Thank you, Ronnie. I'll give one a go. I might even have one I bought for plane journeys somewhere.

I had pain when trying one. Maybe you need a PT consult?

Hi . try putting a pillow behind your head for awhile feel it runs its course sometimes. my neck and shoulders hurt I lay down for awhile. or try a neck pad It closed in the front its all foam and comes in sizes. It works get a soft one and measure the height so it stays under your chin. not expensive. got 2 on amazon.

Hi sorry to be so long replying. (For some reason the notification went into my junk mail!)
Thanks. I'll bear that in mind.
My Pilates teacher (who is also a chartered physiotherapist) and my osteopath both suggest I might try one, but both are reluctant to guarantee success.🕊️
