Here are a few options for the WordPress post_tag description for “手腕肌腱炎” (Tendonitis of the Wrist) in Traditional Chinese, ranging from concise to more descriptive:

**Option 1: Concise (for brevity)**

**Option 2: Slightly More Descriptive**

**Key Considerations when choosing:**

* **Target Audience:** Who are you writing for? Casual readers, medical professionals, or a mix? (Option 4 suits patient education well)
* **Word Count:** WordPress tag descriptions are best kept short and focused.
* **Keywords:** Although not as crucial as the title, consider relevant keywords like “手腕痛” (wrist pain), “肌腱發炎” (tendon inflammation), “治療” (treatment), etc.. Option 3 and 4 do this well subtly by incorporating these keywords into the description.
* **Website Tone:** Ensure the description matches the overall tone and style of your blog or website.

I would recommend **Option 2 or 3** for most WordPress situations. Good luck with your post!
