I have had swelling in the upper left part of my arm for nearly 2 months. My neck and collar bone are now swollen as well. I have left side upper back pain, and in the back of my left leg. Leg foot swells up and down depending on the day but everything else stays consitantly swollen. Extensive testing has been done (MRI s for MS, upper back MRI, chest x-ray, lupus, scardiosis, etc and everything is normal). I do have an elevated white blood cell count (12,500) upset somtach, some stomache ache, extreme fatigue and I just overall do not feel good. Any ideas?
