I got a heat pad on it straight away, my other half made me a peppermint tea and I paced, I literally paced as I couldn't work out what else to do. 10 mins ago, as quick as it came it had gone!
The only way I can explain it is like a dull ache along with very sharp nerve pains, some lasting longer than others, it's awful!
I hope that's all the shoulder pain I'll get! I'm a bit afraid of going to bed tonight and laying down too much and starting it up again!
