I was diagnosed with radiculopathy when I had the neuropathy in a single toe (the very tip). It started with a sharp jolting attack in my groin/leg while walking at the store, and I fell to the floor in pain.
The doctor suspected a nerve, and prescribed gabapentin.
I have not had a groin event since then, but the toe issue started some time after, and continues a year or two now assumed as the lumbar radiculopathy .
Sometimes the gabapentin + naproxen is not enough, so I apply campho phenique with a cotton q-tip as a temporary numbing.
