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 is different from tendinitis, which is inflammation or irritation in the cord or tendon attaching muscle to bone. Older age is associated with bursitis, and one of the most common places it strikes is in the shoulder, which has the greatest range of motion of all the body's major joints.
