Arthritis can be caused by two things. One is hereditary and the other is the result of a previous illness. Within these two situations it is possible to know the initial symptoms of any type, which are pain in the affected area, muscle difficulty or stiffness, redness and swelling.
But this is not all. Depending on the type of arthritis the person suffers from, it is possible to know other symptoms. For example, inflammation in the urinary or digestive system, disability in the knees and hips, bone thickening or skin complaints.
