my 17yearold daughter has had mid to upper back pain for like 3 months, low back pain as well. I have gotten her massages, chiropractor adjustments, gotten an xray which didn t show any spine issues. She also has hip, knee, elbow, ankle pain. Those started about a month and a half ago. Bending down or going up stairs makes her hips and legs shake and feel very weak. Her whole body feels weak. She doesn t have an appetite and feels nauseous after eating. That started about a month ago. She is very cold all of the time. Hands and feet go numb. Has night sweats some.
