Pain and weakness in the joints is often caused by osteoarthritis or rheumatoid arthritis, as these conditions cause inflammation in the joints that can result in poor joint function. Over time, joint damage and deterioration can result in weakness in the joints, according to Net Wellness. Fibromyalgia and lupus are health conditions that may also cause joint pain along with other symptoms, including extreme fatigue. Other joint problems such as bursitis or an injury to the joint may cause joint pain and weakness without other symptoms.
Rheumatoid Arthritis and Osteoarthritis
Joint pain and weakness accompanied by other symptoms may offer clues about their cause. Rheumatoid arthritis is an autoimmune disease that commonly causes pain and weakness in the joints, but also causes extreme stiffness in the joints that's worse in the morning, says the Mayo Clinic. Many people also experience weight loss, fever, swelling and soreness in the joints. And, according to Net Wellness, rheumatoid arthritis joint damage is permanent, which makes early treatment essential to protect the joints. Osteoarthritis can also cause swelling and stiffness in the joints, as well as deterioration of the joint over time, says PubMed Health. Osteoarthritis may develop from simple wear and tear, but may also affect joints following a broken bone or some type of infection.
Fibromyalgia
Fibromyalgia is an autoimmune disease that can cause significant pain and weakness in the joints. According to the Mayo Clinic, fibromyalgia may increase the perception of pain by affecting the way that the brain processes pain signals. Fibromyalgia also causes "tender points," which are specific locations on the body that feel painful and tender to the touch. These tender points typically include the shoulders and between the shoulder blades, front of the neck, back of the head, chest, elbows, hips and knees. Fibromyalgia also tends to cause significant sleep problems and an overall feeling of fatigue.
Joint Injury
An injury to the joint can cause unexplained pain and a weak, unstable feeling. Injuries can strike from active sports such as basketball and tennis, running, kickboxing or even simple gardening or chores around the house. If you've strained or sprained a muscle supporting a joint, you may find that you can't use your knee, ankle, wrist or other joint that you've injured. A fractured bone may also make the joint weak, painful and even unusable.
Dealing With Joint Pain
Resting the joint can help manage pain, but it's important to get a diagnosis for proper treatment. Taking nonsteroidal anti-inflammatory drugs, or NSAIDs, can help with inflammation caused by injury or conditions like osteoarthritis, according to the U.S. National Library of Medicine. Light stretching, gentle massage of the painful joint and soaking in a warm bath can also help to alleviate pain. When your doctor approves, exercise and physical therapy can also help restore joint function and improve strength. Wearing a splint can also offer support for joints weakened by rheumatoid arthritis and other joint problems, says the University of Alabama Health System.
