@curtj Curt, I understand now why she doesn't have Erythromelalgia. Thanks for clarifying. With a diagnosis of Central Sensitization, you might want to study Dr. Norman Doidge on you tube, and hear all his teachings on Neuro plasticity. If she has energy, she really should try to lower her pain through consistent use of neuro plastic pain strategies. You might also want to consider buying the Curable app for your phone or computer, that teaches various methodologies in dealing with pain. It is now on sale for about $50.00. It includes relaxation breathing techniques, "talking to your brain" methodologies in lowering pain, writing/journaling, science lessons to teach you about central sensitization and the neuro plastic brain, etc. I am so glad that sleep is beginning to help your wife, and her pain is lowering a bit. All my best to you, LoriRenee1
