Why were there so few "butt needles" in the past?

10 years ago, when we were sick or caught a cold, most doctors would give us injections. However, in this era, the treatment of injections is becoming less and less common. Then the problem is coming. Why don't doctors use injections to treat diseases now? Actually, it has something to do with the way of injection. Because we all know that it is necessary to take off your pants when you take an injection, it is not a big problem for children to take off their pants, but if the patient is an adult, it will cause an embarrassing atmosphere between doctors and patients. In addition, taking off pants also involves some personal privacy issues.

First, when we were young, we were most impressed by illness. Besides taking medicine, we also have injections. Because before 10 years ago, whenever you had a cold and a fever, the doctor would give you an injection, because this would make our condition get better quickly. However, with the development of the times, people's ideas have also changed, and injection as a medical method has gradually been rejected by doctors.

Secondly, as we all know, when we have a cold and fever, there are generally two treatments. One is injection and the other is infusion. But compared with injections, infusion can make the condition better faster. Generally speaking, the common cold and fever can be cured in two to three days by going to the hospital. This is an important reason why more and more people prefer infusion to injection. In addition, from a medical point of view, injection is to directly input liquid medicine into the capillaries of human muscles. If we often use this method, our bodies will eventually absorb the effects of drugs.

Third, the disadvantages of injection We know that once the injection is wrong, the consequences will be very serious. In addition, if we often get sick, we will have an injection. Our body will produce certain drug resistance, which will have certain side effects on our future treatment of colds and fever.
