Suggest Remedy For Pain And Swelling On Fingers, Elbows, Shoulder And Legs

Every night my pain starts attacking my body, its not in just one place it s my entire body. Along with the pain I have swelling. It attacks my fingers the most, elbows, shoulders and legs. It is so painful that I cant use my hands, I cant even make a tight fist its so painful. In my legs its behind my knees, this pain makes it unbearable to walk. When my body is attacked the pain causes me to have chills, it hurts that bad. It does feel like its in my joints and sometimes feels it could also be muscular. Also, within the past 4 weeks my entire body has started itching. No rashes just random itching from head to toe. All of this is getting worse daily, can you help guide me please?
