Hi Razzle,
Sometimes it helps to add a topical directly to the most painful areas.
Lidocaine - An anesthetic. Available at 4% OTC. Higher concentrations available by prescription.

Magnesium - As a topical, available as magnesium chloride oil. I find this in a light base which sprays on topically. This is usually more expensive than the sulfate lotion.
Magnesium is also available as magnesium sulfate lotion (Morton's Epsom Lotion), which is inexpensive and available at Walmart. (Quite popular as it's inexpensive and does not stain clothing, bedding.)
Capsaicin- This is from hot chili peppers and is a counter-irritant. Many neurologists suggest this as an option. If you try this one, please be very careful in handling this, as you don't want to get any in an eye or places you don't intend to be exposed to capsaicin. Start at the lowest strength first and it this is helpful, you may eventually work your way up to the stronger strength. (I have tried this, repeatedly, on feet and lower legs. I have found this burns far too much, too irritating to my skin and more difficult to use, overall.)

Topicals may be used as a primary approach to neuralgia or as an additional approach to taking systemic medications. Topicals can be convenient, in that people can take containers with them to work, etc., and re-apply when needed.
Hope you find relief soon.
