Phil, I didn't say I've never taken pain killers. I said I didn't need them after my tooth extraction. Yes, I've got a cabinet with varying strengths of pain killers. The chemo used for my breast cancer caused severe neuropathy in my feet. I could not have made it through a day or night without some serious pain relief. As the neuropathy progressed, the doctor increased the strength. I asked about doubling up on the strength I was already taking, and the doctor said no, the main ingredient is mixed with an nsaid, and doubling the dose would double the nsaid. I was to take the stronger dose instead.
It takes time, but the neuropathy does decrease after treatment, but never completely goes away. Sometimes weather changes will trigger a flare up. The degree of pain from the flare up varies, so I dose accordingly.
