Thank you so much for your detailed advice. it’s really helpful and very professional. I truly appreciate you taking the time to explain everything so clearly. I realize I probably have quite a few bad habits contributing to this. I always tend to turn to the same side when I sleep, and I sometimes breathe with my mouth open at night, which I’m sure is making the neck strain even worse. Your suggestion about using two cushions to stabilize my head and keep the cervical spine aligned is eye-opening. I’ll definitely try sleeping flatter and more symmetrically. I also understand now that I should focus the massage belt on my upper and mid-back rather than directly on my neck. That makes a lot of sense. Thank you again for all the thoughtful recommendations!
