Rolling and puckering of the needle for an IV is usually caused by the fact that the injected medication does not enter the blood vessels and accidentally flows outside them. In this case, you should immediately apply local pressure to the back part of the hand where the puckering occurs, but never rub it with your hand to avoid bleeding. In addition to this, the needle needs to be removed and reintroduced, preferably in the other hand, and try to pick a relatively thick vessel. If there is redness and swelling in the hand where the needle was previously rolled, and it is painful, a clean towel can be dipped in hot water and covered over the hand, or a hot compress can be applied with a bottle filled with hot water. In addition, sliced potatoes can be applied to the swollen area to reduce the swelling, which usually only takes 2-3 days. And in the process of the drip, the hand with the needle should not move freely to avoid rolling the needle. If it is in colder weather, it is best to carry a hot water bag and place it under the hand where the drip is injected to prevent getting cold.
