[PhD Explains a Complex Medical Case] Severe Finger Tingling – The Answer May Surprise You!

He has tingling and numbness in the right three fingers, indicating a nerve issue. Initially, everyone assumes it’s ulnar nerve damage due to symptoms in the little finger. However, it’s more complex.

The ulnar nerve controls sensation in the little finger and half of the ring finger. Yet, the patient experiences symptoms in three fingers. The middle finger and half of the ring finger are controlled by the median nerve, suggesting damage to two nerves. Additionally, loss of reflexes on the right side indicates radial nerve involvement. Given the multiple nerve issues, brachial plexus injury is suspected.

Regarding the location of the damage, brachial plexus injuries commonly occur at three points: near the scalene muscles, beneath the pectoralis minor, and at a point under the collarbone’s lateral third division. In this case, the injury to the brachial plexus is specifically in the pectoralis minor region.

As for the type of damage, brachial plexus injuries often result from inflammation or entrapment. I suspect entrapment of the brachial plexus at the pectoralis minor, as pressing on this area radiates tingling to the hand, and the patient feels relief upon relaxation.

The 【Yunmen point】 is located where the pectoralis minor attaches to the coracoid process of the scapula. Acupuncture at this point can help relax the brachial plexus and relieve finger tingling.

I hope this explanation helps understand the medical case.

Thanks

他右手的三根手指有麻木和刺痛，这表明存在神经问题。一般情况，人们通常会认为是尺神经受损，因为小指麻木刺痛。然而，情况比这更复杂。

尺神经控制小指和无名指的一半感觉，但患者的症状涉及三根手指。中指和无名指的另一半由正中神经控制，这表明至少有两条神经受损。此外，患者右侧的反射消失，说明桡神经也受到了影响。因此，考虑到多条神经受损，我们应该怀疑是臂丛神经损伤。

关于损伤的位置，臂丛神经损伤常见于三个部位：斜角肌附近、胸小肌下方以及锁骨的外侧三分之一处。在本病例中，患者的臂丛神经损伤发生在胸小肌区域。

至于损伤的类型，臂丛神经损伤通常由炎症或卡压引起。我认为患者的情况属于胸小肌区域的臂丛神经卡压，因为当按压该部位时，麻木感会沿神经放射到手部，而放松胸小肌后，患者的症状明显缓解。

云门穴位于胸小肌附着于肩胛骨喙突的位置。针刺该穴可放松臂丛神经，并有助于缓解手指麻木。

希望这个解释能帮助理解这个相对复杂的医学案例。

谢谢！
