When the blisters are large, in order to promote the recovery of the blisters, you can use a sterile needle to puncture the blisters, so that the liquid in the blisters out, pay attention to protect the skin of the blisters, do not tear, and finally disinfect the blisters with iodine vapour to prevent infection.
