What should I pay attention to when picking blisters?

If the blisters or blood bubbles are not big, it is best not to puncture them. Put some iodine on it so that the water and blood in the bubbles can be absorbed slowly. If the blister is large, it can be punctured, coated with mercuric chloride or purple liquid, and wrapped with clean cloth. You can also put on a needle or thread sterilized with alcohol, leave the thread inside and let the water flow out slowly along the thread. In case the blister is self-grinded, and the wound is large, it is easy to be contaminated with dirty things. At this time, it is necessary to disinfect with alcohol or iodine, put some tincture of iodine ointment or oxytetracycline ointment and wrap it with clean gauze. Regardless of the size of the blisters, do not use unclean needles, cones, hairpins, firewood, etc. Pick holes and sprinkle soil to stop bleeding, so as to avoid inflammation, suppuration or tetanus.
