I have been having many problems for 4 years now. I live in BC Canada and am 16 years old. It started out with just some minor knee and ankle pain, now my entire body is in pain. I get bad pains in my ankles, knees, wrists, fingers and left hip. But the pain comes and goes. I also get severe muscle pain and weakness to the point that I have to sit down so my legs don't give out. I also have extreme fatigue (my worst symptom), headaches, sensitivity to most chemicals, sun sensitivity, inability to take a deep breath, burning in my right forearm, my elbow will lock up suddenly, random muscle spasms, chest/rib pain, constantly cold hand and feet, restless leg syndrome, scoliosis, night sweats. Over all it pretty much feels like a nasty flu that has never gone away. All my blood tests and X-rays have come back completely normal though! I was tested for: lupus, hyperthyroid, arthritis, anemia. What could this be??
