Osteoarthritis and rheumatoid arthritis are 2 very common types of arthritis. However, there are also other lesser-known types of arthritis, including gout, tendinitis, and psoriatic arthritis.
As well, there are a number of conditions that are similar or related to arthritis. People with arthritis may suffer from depression. Chronic fatigue syndrome, lupus, and temporal arteritis are related to rheumatoid arthritis because they involve an autoimmune process (where the body is attacked by its own immune system). Plantar
fasciitis, low back pain, and back disorders are related to inflammation of tissue. Carpal tunnel syndrome and sciatica are characterized by the damage to nerve pathways.
