A bacterial infection of the vagina can feel a lot like a yeast infection if the vulval area is itchy or painful. Unlike a yeast infection, the discharge can be dark yellow, green, or brown and it won't smell like bread, it can smell like fish or something rotting.
GERD can and does cause upper back burning sensations that can migrate down one side or both sides of the body to the legs. Sometimes pain or symptoms may occur in the chest or sternum area but not always. GERD can also cause a recurring cough and fatigue.
Pain in the upper right back is usually caused by a muscle or bone problem. However, pain in this location is sometimes caused by a condition affecting an internal organ. The body's pain network sends impulses from the source of the discomfort through nerves to the brain.
