Chest tightness in phytoneurological disorders is mainly relieved by oral medications such as Glutamine and Vitamin B₁₂ as well as self-emotional regulation. It is recommended that patients seek immediate medical attention, while maintaining a positive and optimistic mood. 1. Oral medication: Phytoneurological disorders are mainly caused by factors such as high psychosocial stress, family genetics, and endocrine abnormalities. In addition to chest tightness, patients may also suffer from postural hypotension, gastrointestinal symptoms such as nausea and vomiting, as well as abnormalities of the reproductive system such as irregular menstruation in women. It is recommended to follow the doctor’s instructions to take oral glutamine, vitamin B₁₂ and other drugs. 2. Self-regulation of emotions: Because most of the vegetative nerve function disorders are caused by psychological stress, it is extremely important to learn self-regulation of emotions. It is recommended to find someone to talk to or learn self-regulation to improve the symptoms of chest tightness when you are suffering from boredom and stress. It is recommended to maintain a happy mood in daily life, and actively seek help when in discomfort to alleviate one’s symptoms. When the symptoms are serious, you should seek medical attention.
