The symptoms of a condition with sore weak legs and back muscles

Updated April 17, 2017

Sore muscles and weakness are mostly a result of recreational activities or exercise and tasks that are work related. Although they can be minor, there are more serious conditions that can be the cause. Symptoms of these conditions vary but are all related to pain and soreness.

Tendon Injuries

With a tendon injury, there could be inflammation or tiny tears in the tissues around the tendon. This condition can be a result of constant twisting and movement during activities or on the job. Age is also another cause because tendons can wear out and tear over time. Common symptoms of tendon injuries are pain, tenderness and weakness. Resting, using ice and pain medication are methods of treatment.

Muscle Cramps

Muscle cramps can occur anywhere in the body and are very painful. A cramp is when muscles suddenly tighten or when the muscle contracts. Soreness can last for hours and may be caused by exercising, being overactive and getting an injury. If your muscles are not well stretched or you have poor posture that can bring a cramp on as well. Symptoms of muscle cramps are sore, tight and weak muscles.


Osteoarthritis occurs when cartilage breaks down and the bones rub against each other. The cartilage no longer protects and cushions the joints, resulting in damaged tissue and bones. Osteoarthritis commonly affects elderly people; it happens in the spine, hands, hips, legs and feet. Common symptoms are pain, stiffness, weakness and tenderness. It can be treated with medication if taken on a daily basis but still has a chance of getting worse over time.


Lupus causes the immune system to attack body tissues and cause inflammation and tissue damage. It can affect the skin, joints and most organs as well as the nervous system. Symptoms of lupus are fatigue, skin rashes, fever and muscle and joint pain. Although there is no cure, it can be managed with medications to control the inflammation.
