A feeling of protrusion above the chest and pain on pressure may be associated with costochondritis, sebaceous cysts, boils and other causes. 1. Costochondritis: due to the stimulating effect of inflammation, it may cause a sensation of protrusion above the chest, which may be accompanied by pain on pressure. 2. Sebaceous cysts: If the cysts are large, a rounded bulge can be seen on the skin surface, the local skin is smooth, the boundary of the bulge is clear, and pressure pain can occur. 3. Boils: If the hair follicle is attacked by pathogenic bacteria, it can cause localized inflammatory reaction, which may appear as a lump with pain on pressure. It is recommended that people who feel protrusion above the chest and pain on pressure should go to the hospital in time, clarify the cause of the disease, and carry out standardized treatment under the guidance of the doctor.
