In addition to carpal tunnel syndrome, arthritis is another common cause. Arthritis can affect any part of the body and it is especially common. While there is a wide range of different kinds of arthritis, there are a few particular common types of wrist arthritis. Osteoarthritis pain is very common as you get older and can come on at any age due to overuse. Rheumatoid arthritis is also an all too common cause and it is a condition that will typically affect both of your wrists. Meanwhile, psoriatic arthritis comes along with psoriasis and can cause aching wrists. Expert Tip: Infectious arthritis is one of the times when it is an emergency. If your wrist feels warm and you have a fever over 37.7°C, it is time to go directly to the doctor for a check.
