This is also relevant to MS, in the sense that Peripheral Neuropathy is something that WE might end up with (I have it) . . . but may also be caused by many other conditions/treatments, etc., including chemo:

"What is peripheral neuropathy and how is it related to chemotherapy?

The body's nervous system is divided into two major systems; the central nervous system and the peripheral nervous system. The peripheral nervous system is also divided into two major parts, the somatic nervous system and the autonomic nervous system. The somatic nervous system consists of peripheral nerve fibers that send sensory information to the central nervous system and motor nerve fibers that send signals to skeletal muscle. The autonomic nervous system controls smooth muscle of the viscera (internal organs) and glands.

Peripheral neuropathy results from some type of damage to the peripheral nerves. Certain chemotherapy drugs can cause peripheral neuropathy such as vinca alkaloids (vincristine), cisplatin, paclitaxel, and the podophyllotoxins (etoposide and tenoposide).

Symptoms of peripheral neuropathy:

Numbness, tingling (feeling of pins and needles) of hands and/or feet
Burning of hands and/or feet
Numbness around mouth
Constipation
Loss of sensation to touch
Loss of positional sense (knowing where a body part is without looking).
Weakness and leg cramping or any pain in hands and/or feet
Difficulty picking things up or buttoning clothes"
