How about a cold needle?

No, people have a process of catching a cold, infection-onset-recovery. Everyone is like this, but the reaction is different. Very few people have serious symptoms and signs due to physical factors, and even other diseases are secondary. Most people have a mild reaction and will soon pass. Taking medicine by injection only relieves symptoms and makes the body react less. You can spend a week or two with or without drugs. It is useless to take medicine by injection when you have a cold, and it is not conducive to the improvement of immunity. Experts believe that there are three ways to catch a cold: drink more water, sleep more, and take a lot of vitamin C (above C (1000 mg)). Trust me, you will recover completely.
