A 37-year old female presents to the clinic complaining of severe pain in her left wrist and tingling sensation in her left thumb, index finger, and middle finger, and some part of her ring finger. The pain started as an occasional throb and she could ignore it or take ibuprofen but now the pain is much worse and wakes her up at night. She works as a typist and her pain mostly increases after typing all day. Her right wrist and fingers are fine. Nerve conduction studies reveal nerve compression. Which of the following nerves is most likely compressed in this patient?
- A. Axillary nerve
- B. Musculocutaneous nerve
- C. Median nerve
- D. Ulnar nerve
- E. Radial nerve
Hint
Compare the area of tingling with the skin territories of the main nerves of the arm, and consider which one is vulnerable to repetitive wrist movement.
