Symptoms of needle fainting
Disease description:
I accompanied my friend to the hospital this morning for an injection, but she fainted before the injection was even administered because she's needle-phobic. I'd like to ask, what are the common symptoms of needle phobia?

Vasovagal syncope due to needle phobia, also known as needle phobia or injection phobia, is an intense fear response to needles or injections.
1. Premonitory phase: Patients may initially experience discomfort in the head, upper abdomen, and throughout the body, blurred vision, accompanied by tinnitus, palpitations, pallor, and cold sweats. This phase may be brief, and some patients may not experience it at all.
2. Episode phase: Symptoms worsen further; mild cases may present with dizziness, chest tightness, weak and cold limbs, nausea, vomiting, and loss of consciousness; severe cases may collapse suddenly, gradually lose consciousness, sweat profusely, become pale-faced, experience a rapid drop in blood pressure, and a few may have seizures. Some patients may progress directly to the later stage without obvious symptoms during the episode phase.
3. Later phase: If treated promptly, after recovery patients may still feel fatigued, appear pale, sweat less, and feel drowsy. Mild cases recover relatively quickly, while some patients may experience delayed fainting reactions.
If symptoms of needle-related vasovagal syncope are severe, causing frequent fainting or other complications, prompt medical consultation and examination are recommended.
