@viralviral043: Spinal Stenosis Can Be Mistaken for Poor Circulation in Your Legs Leg cramps when you walk that ease when you sit or lean forward may not be a blood flow problem. Spinal stenosis at L4-L5 or L5-S1 can cause the same pattern, sometimes without any back pain. Save this if your legs get heavy after walking a few minutes. #SpinalStenosis #L4L5 #L5S1 #LegCramps #SpineHealth
