The main symptoms of arthritis include pain, swelling, redness and stiffness of joints. An estimated 350 million people worldwide suffer from arthritis, according to MedicineNet.com.
There are over 100 types of arthritis. However, the most common are osteoarthritis and rheumatoid arthritis, notes WebMD.
Osteoarthritis is a condition relating to the wear and tear of bodily joints due to aging and overuse. People with obesity and those who engage in demanding activities are likely to suffer from this condition because of the pressure exerted on the joints. The condition most commonly affects the hips, knees, spine and feet. Some of the most common symptoms associated with this type of arthritis include deep aching pain, stiffness immediately after rest, having a hard time gripping things, swollen joints and difficulty in bending.
Rheumatoid arthritis is regarded as an autoimmune disorder, which means that the immune system reacts abnormally by attacking joints of the body. People with this condition may eventually experience extensive joint damage and deformities. Some of the most common symptoms of rheumatoid arthritis include painful sensations in the joints, general body weakness, loss of appetite, stiffness and swelling in various parts of the body including elbows, jaws, neck, shoulders and hands.
