Impingement Syndrome - Also known as hypertension, high blood pressure is, by definition, a repeatedly elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above 140 with a diastolic pressure above 90.
Indigestion - Excessive secretion of hydrochloric acid by the stomach cells. Medically known as hyperchlorhydria. Also referred to as heartburn.
Infertility - The diminished ability or the inability to conceive and have offspring.
Insomnia - The perception or complaint of inadequate or poor-quality sleep because of one or more of the following: difficulty falling asleep; waking up frequently during the night with difficulty returning to sleep; waking up too early in the morning; or unrefreshing sleep. Insomnia is not defined by the number of hours of sleep a person gets or how long it takes to fall asleep.
Jaw and face pain - The trigeminal nerve is quite complex. It functions both as the chief nerve of sensation for the face and the motor nerve controlling the muscles of mastication (chewing). Problems with the sensory part of the trigeminal nerve result in pain or loss of sensation in the face. Problems with the motor root of the trigeminal nerve result in deviation of the jaw toward the affected side and trouble chewing. The cranial nerves, the trigeminal nerve included, emerge from or enter the skull (the cranium) as opposed to the spinal nerves which emerge from the vertebral column.
Knee pain - Causes of knee pain include injury, degeneration, arthritis, infrequently infection and rarely bone tumors.
Menopausal symptoms - Natural menopause occurs when the ovaries naturally decrease their production of the sex hormones estrogen and progesterone; there are no menstrual periods for 12 consecutive months.
Migraines - A migraine headache is a form of vascular headache. Migraine headache is caused by a combination of vasodilatation (enlargement of blood vessels) and the release of chemicals from nerve fibers that coil around the blood vessels. During a migraine attack, the temporal artery enlarges. (The temporal artery is an artery that lies on the outside of the skull just under the skin of the temple.) Enlargement of the temporal artery stretches the nerves that coil around the artery and causes the nerves to release chemicals. The chemicals cause inflammation, pain, and further enlargement of the artery.
Multiple Sclerosis - Abbreviated MS. A disease of the central nervous system (CNS) marked by numbness, weakness, loss of muscle coordination, and problems with vision, speech, and bladder control. MS is an autoimmune disease in which the body's immune system attacks myelin, a key substance that serves as a nerve insulator and helps in the transmission of nerve signals. The progress, severity and specific symptoms in MS are unpredictable. One never knows when attacks will occur, how long they will last, or how severe they will be.
Muscle Tension/Spasm - A brief, automatic jerking movement. A muscle spasm can be quite painful, with the muscle clenching tightly. Spasms in various types of tissue may be caused by stress, medication, over-exercise, or other factors.
Muscular Dystrophy - One of a group of genetic diseases characterized by progressive weakness and degeneration of the skeletal or voluntary muscles which control movement.
Neck pain - Pain located in the neck is a common medical condition. Neck pain can come from a number of disorders and diseases of any structure in the neck. Neck pain is also referred to as cervical pain.
Neuralgia/Neuritis - Inflammation of nerves.
Neurosis - A chronic disorder featuring irritability of the nervous system (nervousness) and characterized by anxiety or extreme behavior dedicated to avoid anxiety situations.
Osteoporosis - Thinning of the bones with reduction in bone mass due to depletion of calcium and bone protein. Osteoporosis predisposes a person to fractures, which are often slow to heal and heal poorly. It is more common in older adults, particularly post-menopausal women; in patients on steroids; and in those who take steroidal drugs.
PMS - A combination of physical and mood disturbances that occur in the last half of a woman's menstrual cycle after ovulation and normally end with the onset of the menstrual flow.
Pain - The International Association for the Study of Pain defines it as: An unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage. It is useful to distinguish between two basic types of pain, acute and chronic, and they differ greatly.
Parkinson's Disease - Parkinson's disease belongs to a group of conditions called motor system disorders. The four primary symptoms are tremor or trembling in hands, arms, legs, jaw, and face; rigidity or stiffness of the limbs and trunk; bradykinesia or slowness of movement; and postural instability or impaired balance and coordination. As these symptoms become more pronounced, patients may have difficulty walking, talking, or completing other simple tasks. The disease is both chronic, meaning it persists over a long period of time, and progressive, meaning its symptoms grow worse over time. It is not contagious nor is it usually inherited - that is, it does not pass directly from one family member or generation to the next.
Pes Planus - More commonly known as fallen arches, Pes planus can occur from birth and is not always a medical problem (pathologic). It can also occur over time from degeneration of the cartilage and ligaments that support the arch of the foot.
Poliomyelitis - An acute and sometimes devastating viral disease. The virus enters the mouth and multiplies in lymphoid tissues in the pharynx and intestine. Small numbers of virus enter the blood and go to other sites where the virus multiplies more extensively. Another round of viremia (virus in the bloodstream) leads to invasion of the central nervous system (CNS), the spinal cord and brain.
Poor vision, central retinitis - Any one of a large group of inherited disorders in which abnormalities of the photoreceptors (the rods and cones) in the retina lead to progressive visual loss.
Raynaud's Disease - A condition resulting in skin discoloration of the fingers and/or toes when a person is exposed to changes in temperature (cold or hot) or to emotional events. This condition can occur alone or as a part of another disease (such as rheumatoid arthritis). When the condition occurs alone it is referred to as "Raynaud disease" or primary Raynaud phenomenon.
Sciatica - Pain resulting from irritation of the sciatic nerve, typically felt from the low back to behind the thigh and radiating down below the knee. While sciatica can result from a herniated disc directly pressing on the nerve, any cause of irritation or inflammation of this nerve can reproduce the painful symptoms of sciatica.
Shoulder pain - Pain in the shoulder due to an injury or disease. As an extremely mobile joint that plays a central role in the action of a major extremity (the arm), the shoulder is at high risk for injury. An injury can involve the ligaments, bursae, or tendons surrounding the shoulder joint, the cartilage, menisci (plural for meniscus), or bones of the joint. Pain can also occur in the shoulder from diseases and conditions that involve the shoulder joint, the soft tissues and bones surrounding the shoulder, or the nerves that supply sensation to the area.
Sinusitis - Sinusitis is inflammation of the lining membrane of any of the hollow areas (sinuses) of the bone of the skull around the nose.
Stroke residuals - A stroke is the sudden death of brain cells due to a problem with the blood supply. When blood flow to the brain is impaired, oxygen and important nutrients cannot be delivered. The result is abnormal brain function. Blood flow to the brain can be disrupted by either a blockage or rupture of an artery to the brain.
Synovitis - Inflammation of the synovial membrane, the lining of the joint.
Systemic Lupus Erythematosus - A chronic inflammatory condition caused by an autoimmune disease. An autoimmune disease occurs when the body's tissues are attacked by its own immune system. Patients with lupus have unusual antibodies in their blood that are targeted against their own body tissues. Lupus can cause disease of the skin, heart, lungs, kidneys, joints, and nervous system. When only the skin is involved, the condition is called discoid lupus. When internal organs are involved, the condition is called systemic lupus erythematosus (SLE).
Tension headaches - Tension headaches are usually related to stress. Treatment is via stress reduction, acupuncture, massage, and analgesic medication, such as aspirin (in adults only), acetaminophen, ibuprofen, or naproxen sodium. Analgesics containing caffeine may be stronger. Also called muscle tension headache, stress headache.
Tendinitis - Inflammation of a tendon (the tissue by which muscle attaches to bone). Tendinitis most commonly occurs as a result of injury, such as to the tendons around the shoulder or elbow. It can also occur as a result of an underlying inflammatory rheumatic disease, such as reactive arthritis or gout.
Tenosynovitis - Inflammation of the extensor pollicus longus tendon on the side of the wrist at the base of the thumb. De Quervain's Tenosynovitis typically is associated with pain when the thumb is folded across the palm and the fingers are flexed over the thumb as the hand is pulled away from the involved wrist area.
Thoracic Outlet Syndrome - A condition due to compromise of blood vessels or nerve fibers between the armpit (axilla) and base of the neck, usually due to compression of nerves or blood vessels between the neck and shoulders. Symptoms include pain, arm weakness, and numbness in the hands and fingers.
Tinnitus, nervous deafness - "Ringing in the ears" or another noise that seems to originate in the ears or head.
Tonsillitis - Inflammation of the of a tonsil, typically as a result of infection by either a virus or bacteria.
Toothache - Pain in or near a tooth. Also called odontalgia. The most common cause of a toothache is a dental cavity. The second most common cause is gum disease.
Varicose Veins - A dilated (widened) tortuous (twisting) vein, usually involving a superficial vein in the leg, often associated with the valves in the vein. These visible and bulging veins are often associated with symptoms such as tired, heavy, or aching limbs. In severe cases, varicose veins can rupture, or open sores (varicose ulcers) can form on the skin.
Whiplash - Hyperextension (over-extension) injury to the neck, often the result of being struck from behind. |
