The statement “Tingling in the little finger is a warning against four diseases” is unscientific and not true.
Numbness of the fingers may be due to cervical spondylosis, carpal tunnel syndrome, elbow tunnel syndrome, diabetes, other factors, more than four diseases.
1. Cervical spondylosis: cervical disc lesions may compress the nerve roots, causing numbness in the little finger.
2. Carpal tunnel syndrome: the median nerve is compressed as it passes through the carpal tunnel, causing abnormal sensation in the limb, leading to dysfunction and numbness in the fingers in the innervated area.
3. Elbow canal syndrome: usually refers to the ulnar nerve in the elbow through the ulnar nerve groove compression and resulting in disease, manifested as numbness in the fingers.
4. Diabetes mellitus: long-term poor blood sugar control can cause peripheral nerve damage, resulting in numbness in the fingers.
5. Other factors: for example, cold, emotional excitement, high sugar and high calorie diet, overloading of the upper limbs and poor posture and other factors can also lead to numbness of the fingers.
It is recommended that when patients experience numbness in the little finger, they should consult a doctor in time to find out the cause and standardize the treatment under the doctor’s guidance.
