Emma - Nice to see you are healing. With respect to your neck, sometimes I find that it is actually a muscle tight in my skull. My husband got me an acupressure neck pillow from Amazon called bed of nails - it usually only take a few minutes and I can release whatever is tight.
There is also an acupressure matt that I used ALOT in the weeks after surgery and I am pleased to say I maybe use it once a week now. Guess I need to dust it off for my second surgery 7/15.
Note - both of these were way too much in the first few weeks after surgery.
God Bless,
