Osteoarthritis can cause muscle pain in the affected tissues as well as soreness and stiffness. This pain is most intense during movement and after sleep, according to Healthline.
Osteoarthritis occurs when the cartilage breaks down, becoming stiff and losing its elasticity. With time the cartilage wears away, and ligaments and tendons stretch, leading to joint inflammation and rubbing of bones against each other. The result is the loss of movement and severe pain, says WebMD.
Ways of reducing symptoms of osteoarthritis include exercise, weight loss and managing pain by using heat or cold. Exercise increases the patients endurance and strengthens the muscles around the joints, and weight loss minimizes the stress on joints in the hips and knees, relieving muscle spasms and pain, reports Mayo Clinic.
