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.
Warning. Itchy upper back skin may be caused by an allergic reaction to medications. If you take medications, talk with your doctor. Drugs that commonly cause this issue include antibiotics, narcotic pain medications and antifungal medications, according to MayoClinic.com.
