Nettles (an herb recommended by Stephen Harod Buhner in his book, "Healing Lyme") help me with joint pain. Antihistamines also have helped me with nerve pain caused by RSD/CRPS (severe nerve pain) - histamines function as neurotransmitters in addition to their more well-known role in allergies.
Also, periodic chiropractic adjustments can help keep the structure of your body in alignment to reduce unnecessary wear and tear on joints and reduce chances of nerve compression (& damage).
Proper footwear that support your feet's natural structure can also reduce pain. I had terrible foot pain until I got a good pair of walking shoes plus an arch-supporting insert to put in the shoes.
Vitamin B12 is necessary for nerve repair; deficiency of Vitamin B12 is associated with nerve pain. Some medications (acid blockers such as prilosec, some diabetes medications, etc.) can hinder absorption of Vitamin B12 from your food and thus make taking a supplement helpful.
