Hi, truebeliever. Please keep in mind that the chance of your neck hurting because of a blood clot is very remote. If need be, then talk to some friends about their experiences with neck pain. Or here in the Health Support Forum. Here's the link:

I have lots of neck pain, but it's due to a narrowing of my bone area, leading to pressing on my spinal cord. I've also had neck pain because of muscle strain.
How about finding some things to distract yourself? Watch a good TV show or movie, visit a friend, read a good book. Those are ways I also help my pain.
You will be okay, dear one.
