I have been through a spinal fusion and chemo for breast cancer. I'm having neuropathy in hands and feet. My hip is on fire and shoots pain down into my leg. My buttocks start to burn when I sit in any chair except my car seat. I cannot sit to watch TV or to read. When I walk my hip, back and buttocks are fine. I sleep well. Could the chemo have exacerbated a damaged nerve across my hip which was identified when I had surgery? Could it be causing the tingling, burning sensations in my buttocks? Is this permanent. I am 68
