"At some point during this period I read one of Dr. Sarno’s books. His theory is that long periods of pain are not due to actual injury, but rather an emotional problem causing e.g. muscles to tense up or reduced blood flow. There are quite a few people who have had their pain go away by reading one of his books and doing some mental exercises. [... it works, then it stops working, author makes tenuous connection to the cold in their office...] I started wearing a sweatshirt and hand warmers at work, and I avoided caffeine on the days I went to the office. The pain went away, and so far hasn’t come back." Good for them. Sounds like a particular case, but I guess if you feel uncomfortably cold in your office, you should do something about it.
