Apart from fibromyalgia multiple joint pain is seen in hypothyroidism, low Vitamin D levels, Low Vit B12 levels, anemia, Hasimotos thyroiditis, gout (can sometimes cause multiple joint pain), rheumatoid arthritis, osteoarthritis, SLE, electrolyte disturbance particularly those involving calcium and magnesium, parathyroid gland problems, chondrocalcinosis and chronic fatigue syndrome. Menopause is often associated with Vit D and calcium disturbances and hormonal disturbances causing multiple joint pain. Please talk to your doctor regarding these and get yourself examined accordingly. Probably thyroid related causes have been ruled out. Since you have chest congestion, possibility of associated heart involvement should be looked at. Asthma and allergic bronchitis ae the other possibilities.
Do discuss this with your doctor and get yourself examined. Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
