Lumbar Trouble Flaring Up

My cervical spine was almost healed a few days ago, but my lumbar spine problem has flared up again.

Standing is fine, but sitting down is difficult.

I really admire my cousin; he can type standing up. The captain tried it and couldn't get used to it at all.

I really wish Wei Tianchen would give me an acupuncture treatment. So I had to get up and update again.

It's a good time to organize the outline, review the previous text, and refine some new ideas.
