Its interesting that my doctor in the past has told me that I have some fibromyalgia (if I spelled it correctly, I dont know)  and an enlarged heart from being a dancer and having been quite active in my life.  Now, when I wake up, its like I have to have my upper back massaged very hard just to get up out of bed.  Its like my lungs in the back need to be massaged before I can get my body and heart working properly and before I can really move. Why is this?  After the massage, Im fine every day.
Thanks for your question on Chat Doctor. I can understand your concern. Fibromyalgia can cause muscular spasm. So when you massaged that muscle, it releases, and you feel better. So possibility of back muscle spasm is more likely in your case. So follow these steps for better symptomatic relief in muscular spasm. 1. Sit with proper back support.2. Avoid sudden jerky movements of back and forward bending.3. Avoid heavyweight lifting and strenuous exercise.4. Apply warm water pad on affected areas.5. Take muscle relaxant thiocolchicoside if needed.6? Take calcium and vitamin D 3 supplements. Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
