i too have that problem
my lupus doctors have sent me to physical therapy and they are doing leg strengthening exercises with me. i can go up and down my steps now and don't have as much pain. our muscles tend to get weak and we need to keep our blood flowing. of course with the light headedness i can't answer for anyone else but you should talk to your doctor. i know mine come from TA. so make an appointment and tell your doc whats going on. all symptoms should be evaluated.
