Hello, I am four weeks postpartum & breastfeeding. I have been experience extreme stiffness & tenderness in my upper neck / base of my skull. It is sometimes accompanied by a feeling of sore throats or ear infection however no infection is present. I am also getting flushes of heat, tingling & rash on & around my face & neck...Always in the evening. I have had a CT scan with normal results, blood work with normal results but feel so strange & sore any ideas of what I might be dealing with?
