I'm doing cervical spine traction right now... it makes my head hurt but I've found ways to do it that are less uncomfortable.

My story is similar to others here, I'm a lifelong athlete with some injuries that are exacerbated by computer usage. I now stand all day, every day with a monitor at head height, which has been the most impactful lifestyle change. Otherwise I do stretching, some exercises like in this article, deep breathing, and massage.

Looking forward to getting back to lifting and sprinting full-time, meanwhile though my cervical spine needs to become more stable. I'm never going back to sitting at a computer, because I literally can't! I suppose that's good ultimately but I do find it hard to concentrate on certain things while standing.
