In Tinel's sign interpretation, distal tingling along nerve distribution suggests what?

• A. Muscle strain.
• B. Nerve irritation.
• C. Vascular compression.
• D. Joint laxity.

Answer: (B)

Tinel’s sign tests nerve irritability. When you tap over a nerve and a tingling sensation or an electric shock travels distally along the nerve’s path, it means the nerve is irritated or entrapped and more easily excitable. This is a hallmark of neuropathic or compressive nerve conditions, like carpal tunnel syndrome. Muscle strain would cause muscle pain and possible weakness, not a paresthetic tingling that follows the nerve. Vascular compression tends to cause ischemic pain or color changes rather than nerve-type tingling. Joint laxity affects stability and movement, not a distal nerve-directed tingling response.
