At work, many patients always come to ask me:
I didn’t seem to be very nervous or scared before the injection or blood drawing, but when the needle was inserted or the blood was seen, my eyes were dark and even fainted! What the hell is going on here?

Blood dizziness is similar to fear of seeing snakes, spiders, strangers and the opposite sex. It is a psychological problem. It is different from carsickness and seasickness, which is a physiological problem of inner ear balance organs.
The occurrence of needle sickness and blood sickness is due to the overactive vasovagal nerve reaction, which leads to slow heart rate, lower blood pressure, weak pulse, and even sudden unconsciousness and direct fainting.

Generally, before needle sickness and blood sickness occur, the body will have some hints, such as dizziness, palpitation and nausea, limb weakness, sweating, etc. If you have these feelings, you must realize that you may be dizzy…
