SORRY GUYS........I didn't reply cos I went away on monday and only came home today.
Well monday was AGONY!! took painkillers like toffee's then cured it with plenty of beer
.
Tuesday it was feeling a little better til kids dragged me into swimming baths on hols
Wednesday could move it a bit more freely.
Thursday much better.
Today, a heck of a lot better. My shoulder still gets twinges, but my neck is doing a heck of a lot better. Still can't figure out what I had done!! But I just hope it isn't a re-occurring thing because it was very very painful.
Thanks for your suggestions. And if it ever comes back I will seek medical help.
