This can be very difficult to treat.
Working through possible causes is critical as a first step. Local infections or irritations, or itching as a sign of a systemic problem like crohn's should be addressed directly. If no clear cause, a very short course of topical steroids
can help, but caution with too strong or too long. Some rx meds can help (elavil
). Omt & acupuncture
have helped my patients.
