As you know many of us PD patients have trouble sleeping at night. We awaken frequently at night every few hours due to various reasons (difficulty moving and turning in bed, muscle cramping, frequent trips to the bathroom to urinate, etc.) I have been having an issue with numbness to the back of my head as I lay on my back sleeping which wakes me up frequently at night. I have had PD for 11 years and this problem has been getting progressively worse. I have tried various pillows none of whch have helped. My neurologist calls it occipital neuralgia or numbness. Has anyone else out there experienced it and have you discovered anything that helps remedy the condition?? Thanks for your help!!
