ScienceDaily (June 7, 2011) — As warm weather arrives and the great outdoors beckons, more and more men and women will be taking to the trails, the beaches, or their yards and gardens, embarking on physical activities that may result in sore, aching, swollen joints. While it may be tempting to ignore these aches and pains or treat them with a little over-the-counter liniment, a wiser choice is to visit a physician who can determine if the symptoms are due to bursitis, inflammation of the fluid-filled bursae, or sacs, that surround and cushion the joints.
