Hi Doctor, I am a female 54 yrs old. My lower rt back is quite painful when I am up and moving around. I get soreness also down my rt thigh to my knee. I've been lifting barbells with my group gym class past few weeks and I am a downhill skier. It goes away when I rest. Today my rt leg felt weak going up stairs. Should I see an Ortho Dr. or just rest more? Thanks for your time. Carolyn
