This is an autoimmune disorder and according to Troum, it can damage all your joints if not treated on time. People having lupus have an overactive immune system that can effect joints, blood, skin and other organs too, including the kidneys.
The symptoms of lupus are different for everyone but usually, they are intense pain in the joints, swelling and the patient may get a butterfly shaped rash on his cheeks.
There are other symptoms too, that include hair loss, memory disorders, trouble in breathing and dryness in the eyes and mouth.
Gonorrhea is basically a sexually transmitted disease (STD) but it does not only effect the genitals but can also effect the joints badly, in the form of gonococcal arthritis. This is more common in women as compared to men and sexually active teen girls are the major target.
According to Troum, people having gonorrhea may develop one hot, red, swollen joint (in some cases, different large joints can be effected too) in addition to other symptoms of STD. This also causes a burning sensation while urination and increase in vaginal or penis discharge.
