Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Given symptoms are not due to cervical spine lesion or disease, neither the disease is given for that. The symptoms, like stomach upset, fatigue, lack of sleep seems to be due to functional disorders and it could be fibromyalgia, IBS, anxiety and depression, even the given medicines indicated for that only. You can try some aerobic exercise. Also, try to be positive and stop worrying. Hope I have answered your query. Let me know if I can assist you further.
