Arthritis causes a reduction in cartilage (which increased the friction) between the joints. When cartilage becomes damaged or worn down, the affected joint usually becomes inflamed and restricts motion, causing pain. Osteoarthritis gradually develops as we age, whereas Rheumatoid Arthritis often has system-wide symptoms and a genetic relationship.
Carpal Tunnel Syndrome
Compression of the median nerve in your wrist may cause numbness, tingling, weakness and pain in your hand (specifically the palm, thumb, index, middle, and the thumb side of your ring finger). Repetitive motions with your hands, or swelling in your wrist may aggravate the nerve and will cause symptoms based upon the severity of compression.
Complex Regional Pain Syndrome
Chronic progressive disease that commonly affects the extremities by causing severe pain, swelling, and noticeable changes in the skin. The cause of CRPS is unknown, but is thought to be a result from damage to the nervous or circulatory system. Blood flow and sensation are no longer properly regulated and may cause various problems in the muscles, bones, nerves, and skin.
Radicular Nerve Pain
Peripheral nerves in the extremities may cause pain if they are either inflamed or compressed when they enter the spinal column. Osteoarthritis or disc herniations may cause numbness/tingling, burning, or shooting pain from the spinal column down the affected extremity.
