Hi, The shoulder blade pain is less likely to connected with the menopause or the cold medications and more likely to be as a result of your neck posture while sleeping and particularly when awake. It s advisable to minimize mobile phone use and to use a normal chair (avoiding recliners) for a period of 3 weeks and if the symptom is still persisting, please consult an orthopedic surgeon. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. John Chacko, Orthopedic Surgeon
