Rheumatoid arthritis is symmetric, which means it affects the same locations on either side of the body. It also usually affects the small joints of your hands, wrists, and feet. But, unlike rheumatoid arthritis, lupus-caused arthritis does not wear away at your bones.bout 95 percent of people with lupus experience arthritis, which is joint inflammation, or arthralgia, which is joint pain.
Anaphylaxis is a severe, life-threatening, systemic allergic reaction that is almost always unanticipated and may lead to death by airway obstruction or vascular collapse.
If you come in contact with something to which you are allergic, your immune system considers it dangerous and releases a chemical called histamine to counteract it. The release of histamine can cause a variety of symptoms, including a skin rash, headache, sneezing, runny nose, swelling, nausea and diarrhea. The most severe reaction, known as anaphylaxis, can be life-threatening. If the allergen is something you breathe in, your reaction will most likely affect your eyes, nose and lungs. If the allergen is something you consume, youâre more likely to have symptoms in your mouth, stomach and intestines.
