You sound stressed out. My neck and shoulders are usually tense most of the time. Sometimes as hard as rock...and nothing but muscle relaxants really seem to work. Even the strongest massage doesn't usually do much. My friend called it a frozen shoulder. I used a lot of hot rub products when it gets really bad, or a muscle stimulator. I believe it is our autonomic (automatic) nervous system doing it, and I don't think you can do much about it except relaxation exercises and medications.
