What is Anesthesia Dolorosa?
Anesthesia dolorosa (AD) is a rare condition that leads to pain in one or more areas of the face that are numb to the touch. The term "anesthesia dolorosa" translates to "painful numbness." This condition is similar to trigeminal neuralgia (TN), but while TN is characterized by short, intermittent bursts of electric-like pain, the pain associated with AD is constant and usually feels burning or jabbing.
Symptoms
The main symptom of anesthesia dolorosa is facial numbness along with pain. The pain can manifest as:
- Squeezing
- Burning
- Aching
- Pressure
- Heaviness
- Tightness
Causes
AD occurs due to nerve damage that interrupts nerve impulses. This can result from a traumatic injury, an underlying condition, or previous treatments involving the trigeminal nerves.
Risk Factors
The risk factors associated with AD include previous medical procedures that damage the trigeminal nerve or trauma to this nerve.
