There a LOTS of different causes of neck pain & headaches - it's very common for your Trapezius muscles to contribute..! So let's take them out of the equation!
You may feel pain where you're pinching or even your headache or referred pain into other places - if it's too painful, pinch a little less firmly..
But you certainly want to feel it!
Moving your muscle through its range and pinching it at the same time allows your muscle to remember that it's ok to relax again ... The whole principal of massage ..!
It's not a cure (well it can be if its the only source of your pain..!) but it has helped a lot of people (including me!) in daily pain management!!
And remember to get it checked out if it doesn't go away! There is someone who can help! I can help you find someone in Australia if you need..! It's much nicer not to live in pain!!!
