回复：谢谢分享。不过有些疼痛是无法避免的。

I do not think that you had the right process. To use the pain level measure "the procedure"? that is totally wrong and danger. Where is the ultrasound? where is the epidural ? where is the anesthesiologist and pain management?

-----  " WRONG "!

By the way, I can tell you one way: Current pain medicine can control the pain to the bearable level.
