Just to add, I discussed the topical cream with my neuro. The problem is the depth of the affected nerves. That is, topical creams do not penetrate very deeply. There are creams which are designed for deep penetration to combat nerve pain. A 100 g tube, however, costs $600 here in the US or $220 in Europe, but there is no guarantee that it will work on every patient. Interestingly, the same chemical composition lotion from the vet is 1/3 the cost!
