Irritable bowel syndrome does not go away in the sense that a cold goes away.

Concrete looks permanent. It is not. The same material that holds up bridges and sidewalks can be slowly eaten away by chemistry, by microbes, and by something as ordinary as road salt. Below the surface, concrete is a porous, alkaline material — and that combination of pores and high pH is exactly what makes it … Read more
Elasticized stockings apply gentle, graduated pressure to the leg. That pressure is highest at the ankle and steadily decreases as the stocking rises toward the knee or thigh. This external squeeze helps the veins and calf muscles push blood back up toward the heart and reduces the pooling of fluid that causes swelling. They are … Read more
