Hi I had gone through the question and understand your concern. See , Staph infections can range from minor skin problems to endocarditis, a life-threatening infection of the inner lining of your heart (endocardium). As a result, signs and symptoms of staph infections vary widely, depending on the location and severity of the infection. Now when the staph infection enters blood , it causes a condition called Bacteremia , also known as blood poisoning. Bacteremia occurs when staph bacteria enter a person s bloodstream. A fever and low blood pressure are signs of bacteremia. The bacteria can travel to locations deep within your body, to produce infections affecting: 1 Internal organs, such as your brain, heart or lungs 2 Bones and muscles 3 Surgically implanted devices, such as artificial joints or cardiac pacemakers I hope this information helps. Let me know if you have any other queries. Thank you.
