Internal Hemorrhoid â A swollen vein inside of the anal canal. Internal hemorrhoids often are small, but they can be large and bulge out of the anus. If they bulge out and are squeezed by the anal muscles they can be particularly painful, even more so if the muscle cuts off the hemorrhoids blood supply.
Dear Reader: Arthritis and bursitis can be difficult to differentiate. Arthritis is joint inflammation with associated degeneration of connective tissue and bone. Bursitis is inflammation of the bursa, a sac-like cavity surrounding joints that is filled with fluid that reduces friction caused by movement.
Bursitis and tendinitis are both common conditions that cause swelling around muscles and bones. They occur most often in the shoulder, elbow, wrist, hip, knee, or ankle. A bursa is a small, fluid-filled sac that acts as a cushion between a bone and other moving body parts such as muscles, tendons, or skin.ursitis occurs when a bursa becomes swollen. A tendon is a flexible band of tissue that connects muscles to bones. Tendons can be small, like those found in the hand or ankle, or large, like the Achilles tendon in the heel. Tendons help create movement by making the muscles push or pull the bones in different ways.
