Current Health: Excellent health; 59 year old; good eating habits; non-smoking; no drugs; regular exercise program. Problem: 2 years of increasing pain in right leg (not knee, ankle, or hip); excrutiationg pain "only" when in an a horizontal position (most noticeable in bed at at night), walking upwards (like a staircase), or stationary in a vehicle for long periods of time (more than a half hour). When I am upright, working (accountant), and even when exercising, I rarely feel any pain at all. Current medical to date: MRI (lumbar) and bone scan; all negative results. Question: the pain is real; where do I go next?
