当忙碌的手受伤时：手的疼痛会告诉你什么

**By Julie Roberts, MD**

手指麻木？手腕痛？手疼吗？随着流感大流行，我们中许多有幸在家工作的人正在处理新的或恶化的手和手臂疼痛，这些疼痛与奇怪的工作环境和不健康的姿势有关。不仅如此，我们这些人谁终于得到了拖延已久的庭院改善项目可能会发现，这些活动是触发慢性和重复的过度使用的伤害。例如，修剪灌木，耙树叶，或油漆可能会导致肌腱炎爆发或加重原有的条件，如关节炎。

这里有两个常见的手的问题，人们可能会有由于在家工作和其他动手活动，我们正试图在大流行的结果。

Carpal Tunnel Syndrome

Have numbness and tingling in your hands? It might be related to carpal tunnel syndrome.

腕管综合征（CTS）是由腕部正中神经受压引起的。症状包括手部麻木和刺痛，尤其是拇指、食指和中指。人们常说手指有“针扎”的感觉。早期CT，你可能会在夜间出现症状。你可能会在晚上醒来时手睡着了，不得不摇动它们来恢复知觉。大多数人睡觉时双手卷曲，手腕弯曲；这种姿势给腕管带来很大压力。

Another symptom of CTS is hand fatigue with repetitive activities. Less commonly, people will have pain in their hands and forearms related to CTS. If you wake up at night several times a week, or have symptoms throughout the day, you should be evaluated for CTS. There are other, less common causes of numbness and tingling in the hands, and an exam and thorough evaluation is necessary to make the correct diagnosis and discuss treatment.

CTS的治疗方案从活动调整和夜间夹板治疗轻微症状开始。更中度和严重的症状可能需要手术释放腕管。腕管松解术有两种主要方法，包括传统的开放入路和微创内窥镜松解术，这两种方法已被证明可以更快地恢复工作。

触发指

手掌痛吗？这可能与触发指有关，一种称为腱鞘炎的肌腱炎。

触动手指的症状可能包括手指的咔嗒声、抓伤和锁定，通常与手掌疼痛有关。弯曲手指的肌腱穿过一个叫做“滑轮”的狭窄通道。在扳机手指中，肌腱和滑轮都会发炎。重复性的活动，比如给花园除草或修剪树篱，会加剧这种炎症。许多人在重复活动或早晨会出现症状，因为我们的手在晚上会自然肿胀。扳机手指不会出现麻木或刺痛感。有趣的是，人们谁得到触发手指是倾向于腕管，反之亦然。

Trigger fingers are often treated with steroid injections. One or two injections are often all that is needed to decrease the swelling around the tendon to allow it to glide smoothly again. Steroid injections can cure trigger fingers and symptoms never return. If a trigger finger is persistent, then you might have a discussion with your doctor about surgical release.

保持符合人体工程学的工作姿势很重要，以防止CTS、扳机手指和其他与过度使用和重复运动有关的手和手臂状况。坐在与工作站成直角的位置，肘部、臀部和膝盖呈90度弯曲，显示器与眼睛平齐。任何姿势在长时间后都会造成劳损，所以移动也很重要！休息一会儿起床，四处走走，舒展筋骨。

When symptoms are persistent, despite initial care, it can be advantageous to see a specialist to confirm diagnosis and discuss further treatment options. If you’re experiencing hand pain, numbness, or tingling, see a specialist when symptoms have persisted or worsened, despite trying rest and activity modification for a few weeks.
