Which common symptom is primarily associated with nerve irritation or damage?
- A) Deep bone ache
- B) Constant throbbing
- C) Tingling, burning, or "pins and needles" (Paresthesia)
- D) Joint swelling (Edema)
When a nerve is irritated, compressed, or damaged, it sends abnormal electrical signals to the brain. This is often described as "paresthesia," a sensation that occurs without an apparent physical stimulus.
- Common Causes: This is frequently seen in conditions like carpal tunnel syndrome, sciatica, or peripheral neuropathy.
- The Sensation: The brain interprets these "misfiring" nerve signals as tingling, numbness, or a burning heat.
- Diagnostic Clue: Because nerves have specific pathways (dermatomes), the location of the tingling often helps doctors pinpoint exactly where the nerve is being pinched or damaged.
