Egg yolks contain two amino acids and at least one vitamin that contain sulfur. The sulfur is released as the compounds degrade in cooking. Hydrogen sulphide is a physiologically active molecule that is produced naturally by most lifeforms, and is a cellular messenger molecule. It has important roles in many processes.
1 An injury, infection, or an underlying rheumatic condition can cause bursa inflammation. 2  Bursitis is diagnosed by identifying swelling, tenderness, and pain with motion in the affected area. 3  Treatment of bursitis is directed toward reducing inflammation and treating any infection present.
Bursitis can cause pain, localized tenderness, and limited motion. Swelling and redness may occur if the inflamed bursa is close to the surface (superficial). Chronic bursitis may involve repeated attacks of pain, swelling, and tenderness, which may lead to the deterioration of muscles and a limited range of motion.
