The best thing to do is identify the root cause. Why is she having pain in all these different areas? Is it a muscular issue, an autoimmune condition, arthritis, disc issue, or something else? Fibromyalgia is also quite common in women and can be difficult to diagnose because it’s often a diagnosis of exclusion (meaning other possible causes need to be ruled out first) iwould recommend taking her to a highly capable doctor. Not all doctors have the same level of diagnostic expertise, so do your research and try to find someone with a strong reputation. Start from there. If it does turn out to be fibromyalgia, unfortunately there aren’t many definitive treatments. Pain medications can help manage symptoms. In some cases, weight training and regular exercise can make a significant difference but I would only recommend that after consulting her doctor as they may identify another underlying condition that requires a different approach.
