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.

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.
There are 160 bursae in the body. The major bursae are located adjacent to the tendons near the large joints, such as the shoulders, elbows, hips, and knees. Bursitis is inflammation of a bursa. When injury or inflammation of a bursa around the shoulder joint occurs, shoulder bursitis is present. How does a bursa becomes inflamed? A bursa can become inflamed from injury, infection (rare in the shoulder), or an underlying rheumatic condition.
