Fibromyalgia
Fibromyalgia is a common condition characterized by long-term, body-wide pain and tender points in joints, muscles, tendons, and other soft tissues.
Elbow Disorders
Elbow pain can be caused by a variety of problems. A common cause in adults is tendinitis, an inflammation and injury to the tendons-- soft tissues that attach muscle to bone.
Osteomalacia
Osteomalacia is softening of the bones due to a lack of vitamin D or a problem with the body''s ability to break down and use this vitamin.
Osteoporosis
Osteoporosis is the thinning of bone tissue and loss of bone density over time.Osteoporosis is the most common type of bone disease.
Rickets
Rickets is a disorder caused by a lack of vitamin D, calcium, or phosphate. It leads to softening and weakening of the bones.Osteomalacia in children; Vitamin D deficiency; Renal rickets.
Ankylosing Spondylitis
Ankylosing spondylitis is a long-term disease that causes inflammation of the joints between the spinal bones and the joints between the spine and the pelvis.
Costochondritis
Costochondritis is an inflammation and associated tenderness of the cartilage(i.e., the costochondral joints) that attaches the front of the ribs to the breastbone.
Foot Disorders
Pain or discomfort can be felt anywhere in the foot, including the heel, toes, arch, instep, sole, or ankles.
Paget's Disease of the Bone
Paget''s disease is a disorder that involves abnormal bone destruction and regrowth, which results in deformity.
Ulnar Nerve Compression Syndromes
Ulnar nerve dysfunction is a problem with the nerve that travels from the wrist to the shoulder, which leads to movement or sensation problems in the wrist and hand.
Sprains and Strains
Strain refers to damage or tearing of a muscle.When excessive force is applied to a joint, the ligaments that hold the bones together may be torn or damaged.
Joint Disorders
There are numerous joints in the body that act to stabilize and control bony segments. One example is the knee joint, which joins the femur and tibia.
Muscular Dystrophy
Muscular dystrophy is a group of disorders that involve muscle weakness and loss of muscle tissue that get worse over time.
Shin Splints
Shin splints are pains in the front of the lower legs caused by exercise. They usually appear after a period of inactivity.
Legg-Calve-Perthes' Disease
Legg-Calve-Perthes disease is when the ball of the thighbone in the hip doesn''t get enough blood, causing the bone to die.Legg-Calve-Perthes disease usually occurs in boys 4- 10 years old.
Bone Infection (Osteomyelitis)
Osteomyelitis is an acute or chronic bone infection, usually caused by bacteria.Bone infection can be caused by bacteria or by fungus.
Polymyalgia Rheumatica
Polymyalgia rheumatica is an inflammatory disorder involving pain and stiffness in the hip or shoulder area.
Rhabdomyolysis
Rhabdomyolysis is the breakdown of muscle fibers resulting in the release of muscle fiber contents(myoglobin) into the bloodstream.
Spinal Stenosis
Spinal stenosis is a narrowing of the lumbar(back) or cervical(neck) spinal canal, which causes compression of the nerve roots.Spinal stenosis mainly affects middle-aged or elderly people.
Still's Disease (Adult Onset)
Adult Still''s disease is a rare illness marked by high fevers, rash, and joint pain. It may lead to long-term(chronic) arthritis.It is more commonly called adult-onset Still''s disease(AOSD).
Plantar Fasciitis
Plantar fasciitis is irritation and swelling of the thick tissue on the bottom of the foot.The plantar fascia is a very thick band of tissue that holds up the bones on the bottom of the foot.
Dermatomyositis
Dermatomyositis is a muscle disease characterized by inflammation and a skin rash. It is a type of inflammatory myopathy.The cause of dermatomyositis is unknown.
Trigger Finger
Trigger finger is the popular name of stenosing tenosynovitis, a painful condition in which a finger or thumb locks when it is bent(flexed) or straightened(extended).
Cervical Spondylosis
Cervical spondylosis is a disorder caused by abnormal wear on the cartilage and bones of the neck(cervical vertebrae).
Osteochondrosis
The term osteochondroses refers to a group of diseases of children and adolescents in which localized tissue death(necrosis) occurs, usually followed by full regeneration of healthy bone tissue.
Osgood-Schlatter Disease
Osgood-Schlatter disease is a painful swelling of the bump on the front, upper part of the lower leg bone. This bump is called the anterior tibial tubercle.
Shoulder Disorders
Shoulder pain involves any pain in or around the shoulder joint.The shoulder is the most mobile joint in the human body. The rotator cuff in the shoulder is made up of four tendons.
Ankle Disorders
Ankle pain involves any discomfort in one or both ankles.Ankle pain is often due to an ankle sprain. A sprain is an injury to the ligaments, which connect bones to one another.
Knee Disorders
Knee pain usually results from overuse, poor form during physical activity, not warming up or cooling down, or inadequate stretching.
Wrist Disorders
The thumb muscle can become weak, making it difficult to grasp things. Pain may extend up to your elbow.
Hip Disorders
Hip-related pain is not always felt directly over the hip. Instead, you may feel it in the middle of your thigh or in your groin.
Brittle Bone Disease (Osteogenesis Imperfecta)
Osteogenesis imperfecta is a condition causing extremely fragile bones.Osteogenesis imperfecta(OI) is a congenital disease, meaning it is present at birth.
