Pain Management Through Surgery

Severe spasticity in the lower extremities can be associated with pain. In these cases, benefit may be obtained from an intrathecal (within the spine) baclofen pump, which delivers tiny doses of baclofen directly into the spinal fluid by a surgically implanted pump. Morphine can also be delivered this way.

Nerve blocks (injections of local anesthetic into the inflamed nerve) can also be used.

The fifth cranial nerve (trigeminal nerve) controls sensory innervation of the face, sinuses, and teeth, and motor function of the muscles of mastication (chewing).

In severe cases of pain, surgery can be performed to cut some of the spinal sensory nerves. Called partial posterior rhizoto-my, these surgical cuts are irreversible.

In summary, pain can be a significant symptom of MS. A combination of modali ties often provides the best outcome. Physical therapy, emotional support, and drug therapy, along with a trusting relationship between patient and doctor, often prove the most helpful.
