There are many different potential causes of joint pain. Some of the most common causes of joint pain include:
• Arthritis — Joint pain is a common symptom of certain types of arthritis, such as osteoarthritis and rheumatoid arthritis.
• Bursitis — Most commonly caused by an injury or overuse, bursitis is inflammation of the bursae, fluid-filled sacs that lessen friction between moving parts in the body. A common symptom of bursitis is pain in the joint near the inflamed bursae.
• Lyme disease — Joint swelling, pain and stiffness can occur with Lyme disease, a bacterial infection that’s typically caused by tick bites.
• Cancer – Certain types of cancer such as leukemia and bone cancer can cause joint pain.
• Rheumatic fever — Believed to be an immune response to a previous infection, rheumatic fever can cause swelling and pain in the joints.
• Rickets — Most often caused by a vitamin D deficiency, rickets can result in joint pain and swelling
• Bone conditions — Joint pain can be a symptom of certain bone conditions, such as osteonecrosis, osteomyelitis and broken bones.
• Tendonitis — Often caused by overuse and injury, tendonitis is inflammation of a tendon. The condition can cause pain in or near the neighboring joint.
• Sprains — A common injury, sprains occur when a ligament is torn or becomes stretched. Sprains can result in pain and inflammation in the affected joint.
However, there is a great deal of non-specific joint pain that can occur as a result of wear & tear, aging, increased weight, increased activity or occasional heavy lifting.
