What causes my leg muscles to ache when I walk up stairs?
My leg muscles ache whenever I walk up stairs or exert my legs by walking uphill. My blood oxygen level is also low. I have been on oxygen for three months and my symptoms are not as prominent on oxygen. I have had many tests run at the University of Utah including my heart, pulmonary, and vascular system. So far they do not know what is causing my symptoms. My next appointment will be the the neurological clinic. Does anyone have any suggestions?
