Full Answer

An essential tremor is a nerve disorder that most commonly affects the upper body, causing uncontrollable shaking in various parts of the body, reports WebMD. Areas most commonly affected include arms, hands, head, voice box, tongue and chin. The disorder is not life-threatening, and most people live normal lives with minor difficulties. In rare cases of the disorder, there may be problems with balance in addition to the tremors.

Tremors are one of the most well-known signs of Parkinson's disease, reports Mayo Clinic. The disease is progressive, increasingly affecting the nervous system gradually over time. Other symptoms include slowed movement, rigid muscles, impaired posture and balance, loss of automatic movements, speech changes and writing changes. Unfortunately, Parkinson's disease cannot be cured.

Hypocalcemia occurs when the body has an abnormally low level of calcium, reports Healthline. Sufferers may also exhibit symptoms such as seizures, muscle stiffness, anxiety or depression, hypotension and congestive heart failure. Additional symptoms may also include dementia, cataracts, eczema, dry and course skin, parkinsonism and papilledema. This condition may go away on its own, but treatment options include medications and home care.
