In the early stage of the disease, there are only abnormal sensation, tingling and numbness in the limbs, hand and foot spasm and rigidity. When the blood calcium decreases to a certain level, twitchy symptoms often appear, and the fingers of both hands are flexed inward to form an “eagle’s claw”, after which the feet are also tonicly extended. In severe cases, the whole body skeletal muscle and smooth muscle may also be in spasm, accompanied by laryngospasm, bronchospasm, asthma, laryngeal tinnitus, asphyxia, apnea and other critical signs. Myocardial involvement may include tachycardia, diaphragmatic spasm, and occasional erratic rebellion. All of these symptoms can be triggered by infection, overwork and emotions. Women are also prone to attacks around the time of menstruation. When the blood calcium is 7-8 mg%, there may be no obvious clinical symptoms, which is called occult tics. Finger (toe) swelling refers to the increase in size of the tissue due to inflammation or bruising and congestion. Brittle atrophy of the finger (toe) nail is a clinical manifestation of pseudohypoparathyroidism. Patients with pseudohypoparathyroidism often have rough skin, hyperpigmentation, hair loss, brittle and atrophied finger (toe) nails, and even loss of nails; cataracts may occur in the lens of the eye. The main method of treatment for parathyroid disease is to supplement various calcium supplements and vitamin D. It is advisable to enter a high calcium and low phosphorus diet, and it is not advisable to eat more dairy products, egg yolk and cauliflower. If the seizure is mild, 2-3 grams of calcium lactate should be taken orally every day. Severe patients should go to the hospital in order to differentiate from neurosis, epilepsy and idiopathic somatic easy spasms to avoid getting the symptoms wrong.
