Avoid vitamin pills. Real nutrients referred to as "nervines" can be taken to support the healing nerves. I suggest scullcap taken internally. Get a good scullcap extract. You'll need to take it for 4-8 weeks. But you may notice improvement within 2 weeks.
Also, you can apply essential oils of chamomile and lavender on the affected areas (externally). Be sure to make about a 10-20% strength of the oils mixed with olive oil OR almond oil.
