A common symptom of heart disease is shortness of breath, which is caused by the blood being deprived of the proper amount of oxygen. Another common symptom is chest pain or pain down either arm. Other symptoms are palpitations, fainting, emotional instability, cold hands and feet, frequent perspiration, and fatigue.
The pain and burning sensation in the knees is often caused due to the damage to the structures in and around the knee joint. Wear and tear of knee joint cartilage is the most common reason. The other cause can be ligament tear, bursitis. Often, the characteristic burning sensation in the knee joint is due to Iliotibial band friction. It is a common cause for knee pain in athletes. Iliotibial band originates from the hip joint and runs all the way to the knee joint.
If you experience sudden attacks of severe knee pain and your knee also becomes red and hot, the cause is likely to be gout, which is a type of arthritis. Gout is caused by a build-up of uric acid (a waste product) in the body, which can form crystals in the joints. These crystals cause the joints to become inflamed and painful. Gout will cause severe pain in the knee and limit movement of the joint. You may feel pain even when you're resting, including at night.
