回复：请问: 后背总是会有发紧的感觉可能会是什么原因?

Likely related to long hours in unhealthy posture (as every desk worker does each day...). You need spend at least 1/2 -1hr each day on activities homo sapiens were defined for: walking with your two feet, back straight-- and do exercises with non-symmetrical motions of your upper body. Also need to work on muscles on the back.
