Medical conditions causing paresthesias include: carpal tunnel syndrome, diabetes , migraines, multiple sclerosis, seizures, stroke, TIA or transient ischemic attack, underactive thyroid, or Raynaud’s phenomenon.
Paresthesias can also be caused by; remaining in the same position for prolonged periods, injury to a nerve, pressure on the spinal nerves (disk herniation), lack of blood supply to an area of the body, abnormal levels of calcium, potassium or sodium, lack of vitamin B12 or other vitamins, certain medications, toxic agents such as lead, alcohol or tobacco, radiation therapy.

Pericardial Effusion is an abnormal collection of fluid inside the sac that covers the heart. With pericarditis, the amount of fluid increases within the pericardial layers, squeezes the heart, and can restrict the motion of the heart, called a pericardial effusion.
Pericarditis is usually a complication of viral infections, most commonly echovirus or coxsackie virus, and less frequently, caused by influenza or HIV infection.
Infections with bacteria can lead to bacterial pericarditis (also called purulent pericarditis). Some fungal infections can also produce pericarditis.

The hypophysis, or pituitary is a small, pea-sized gland located at the base of the brain that functions as “The Master Gland.” From its lofty position above the rest of the body it sends signals to the thyroid gland, adrenal glands, ovaries and testes, directing them to produce thyroid hormone, cortisol, estrogen, testosterone, and many more. These hormones have dramatic effects on metabolism, blood pressure, sexuality, reproduction, and other vital body functions. In addition, the pituitary gland produces growth hormone for normal development of height and prolactin for milk production.

Composed of blood vessels that carry hormones from the brain to the pituitary and also nervous tissue which transports the hormone ADH to the posterior pituitary.
