In many cases, triggers. Triggers are stimuli and/or lack of stimuli and/or changes in stimuli/status quo; anything the body—and sometimes the mind—is subjected to or deprived of.

The list of potentials is long: foods, supplements, medications, exercise & physical stimuli, environmental conditions (inside/outside the home), mental/psychological stimuli... In short, anything (that we do/don't do—or are exposed to/not exposed to) can be a trigger.

Identifying our individual triggers can be deceptively challenging (especially when we think we have identified all our triggers, yet symptom flares still occur), and requires many skills of a detective—among them attentiveness, diligence, observation, and perseverence. Good record-keeping in a diary/journal/log can be of benefit, as can listening to our bodies, and input of those around us.

Identifying triggers is not (always) easy, but the effort can be worthwhile. It (probably) won't cure neuropathy, but can make it less intolerable, and restore a modicum of control.
