Anybody else suffering pain mostly, or only, at night? Anybody know why Erythromelalgia and/or MPN bone pain can be so much worse at night? I can get through the day, but then most nights, when the pain gets bad, only three 10/325 Hydrocodone will give me any relief. And, I hate taking that much of an opiate so often. It's like it's becoming a way of life. The pain and symptoms are very intense and very real...I can't just call it an addiction to painkillers.
