The person either sits or lies along the way to donate blood, while the doctor sterilizes the area of ​​the whip hand and applies pressure to it with duct tape to fill the veins with blood.

After that, the doctor inserts a sterile needle with a tube and bag to collect the blood, and this method continues for 10 minutes or until the bag is filled.

But usually, once the doctor inserts the needle into the vein, there is a high probability of bruising in its place, so this downside is one of the most common problems associated with donating blood.

If bruising appears, it is recommended to use cold compresses for several minutes every two or three hours, especially during the first 24 hours of donating blood.

It is necessary to consult a doctor if the infection does not stop.

3. Feeling pain

In most cases, donating blood or bad needles is in the midst of the pain.

Sometimes this pain occurs only if the needle is inserted into the body, that is, you should not feel pain throughout the method of drawing the blood.

It is worth noting that you may experience pain at the site of the needle, and during this case, you may need a pain reliever, such as Paracetamol.

4. Feeling sick and terrified

When donating blood, many people experience dizziness, lightheadedness, and nausea, which is exactly why the doctor asks you to sit for a quarter of an hour.

During this phase, the person relaxes, drinks fluids, and eats a lighter meal.

If these symptoms persist, you should change your position with your feet elevated until you feel elevation, and you should also consult a doctor if this condition persists for the time being.

5. The harm of donating blood to others
