Neuroma -- Options

I have had a neuroma (not Morton's -- mine is between the joints of my second and third toes) for nearly two years. I have tried orthotics and they are only slightly helpful when I am actually able to accommodate them in my footwear. I am an avid outdoors-person and there a number of activities I participate in where orthotics are out of the question.

My symptoms typically feel like I am walking on a spiky marble that is lodged under my skin in the affected area. Sitting and removing weight from my foot during a flare up does not provide relief nor do anti-inflammatory meds, ice, chiropractic adjustments, or massage.

I have nerve damage from surgery on my unaffected leg that has me hesitant to try any other remedies without hearing about other peoples' experience. I am told that corti-steroid/alcohol injections are a possibility but that even if they help (temporarily) that they can induce the same sorts of loss of nerve feeling that surgery often results in. I understand that the point is not to feel the affected nerve which is the source of pain, but I do not want to loose feeling in other parts of my foot or into my leg.

Anyone got any feedback for me? I just assume find a way to get rid of this pain altogether as I had to quit running as soon as the problem arose and I am having a harder time staying at my ideal/desired weight since getting the neuroma.
