My wife has extreme nerve pain at night when she is trying to sleep. The pain is excruciating for her. She has seen a neurologist, and waiting to have further MRIs performed. She is taking Robaxin, Gabapentin, Prednisone, and Duloxetine, but still has the episodes at night. Over time we are able to control it with moist heat, but it intensifies so fast that it takes her a while to recover. Is there anything that we can do before she goes to sleep, or after she wakes up with the pain to help prevent these pain episodes?
