As is common with many conditions, there are several reasons one may suffer from pain in their right hand. The conditions can range from minor, such as a simple strain due to overuse/improper use, to severe, such as an acute condition like arthritis. Experiencing pain in your right hand is a malady which a large amount of the population has suffered from at one point, or is currently suffering from; therefore, know that you are not alone. The majority of the population is right-handed, so this injury could cause a significant disruption in one’s daily life, and is not so much of a problem if one’s left hand were to be injured. The typical causes of pain in one’s right hand are strains due to repetitive movements or sprain injuries. Degenerative diseases such as arthritis are a severe case which may cause lifelong problems.
Tendinitis
Barring an injury due to direct physical impact, such as a wound or fall, a hand injury most commonly occurs from overuse and repetitive movement patterns. Minor and temporary pain in one’s right hand due to overuse will strain the joints and muscles in the hand. Tendinitis – which is when the fibrous bands that attach muscles to bones, the tendons, become inflamed or torn – may also be the cause of any discomfort. If one is already suffering from tendinitis, performing repetitive motions like writing, typing, or grasping can further exacerbate the pain.
Carpal Tunnel Syndrome
Right hand pain may also be caused by carpal tunnel syndrome, which is a chronic condition that produces symptoms like tingling, numbness, and weakness in the thumb. With this condition, hand pain typically results from the median nerve when the base of the hand is aggravated by swollen tendons or ligaments around the base of the thumb and wrist. The right hand is commonly affected by carpal tunnel since most people are right-side dominant. Fortunately, this condition is minor, however intense pain or extended numbness may be a sign of an underlying acute condition.
Arthritis
Another very common cause of chronic pain in one’s right hand is arthritis. This disease affects millions of people worldwide. Infectious arthritis can be caused by bacteria or viruses that enter one’s body and lodges itself into a joint in the right hand. Rheumatoid arthritis, an immunological disease, causes people’s immune system to attack the joints of one’s body, leading to stiffness and pain. Wrists and hands are typically the first areas to be aggravated by rheumatoid arthritis. Aside from stiffness and pain, one’s right hand can also become swollen or red with hard, small bumps located beneath the skin.
