Stage 2 �” The Blister

This is when the cold sore starts to get ugly as small blisters will start to form in a cluster on the lip. The itching will increase and you will start to feel some pain. The fluid in the blisters contains particles of the HSV-1 virus and your body will start to fight this by sending white blood cells to the area. The blister stage lasts for 1 to 2 days.

Stage 3 �” Ulcer

About 4 days after the cold sore starts forming the blister will burst and this will cause the uncomfortable ulcer stage. This is considered the most painful stage in the cold sore cycle as the area forms an ulcer and becomes inflamed. The ulcer stage will also last between 1 to 2 days.

Stage 4 �” Scabbing

Once you reach this stage the worst is actually over, but the body is only starting to heal. As the cold sore dries out a scab will form over the area. Cracks and splits will form in the scab, but picking at it will lead to bleeding. The scab will itch as the skin starts to heal, but you need to avoid scratching at it because this could cause bleeding. The scabbing stage could last approximately 4 days before it starts to flake.

Stage 5 �” Healing

Once the scab starts to come off you will enter the last stage of the cold sore cycle which is the healing stage. The skin underneath the scab will be dry and flaky with a pink or red tinge to it. It is important that you moisturize the lips to ensure that the cold sore does not leave any scarring. The healing stage could last up to 5 days.

It is important that you know the stages of cold sores because you will be contagious from the time you feel tingling to the end of the healing stage. This means that anyone who comes into contact with the cold sore could be infected and you could infect others by sharing items that have touched the cold sore. There is very little that you can do to speed up the cold sore cycle other than relieving the itching. Hope now you get an idea on how long does cold sores last.

    It says ‘the healing stage could last up to 5 days’. Well mine have been scabbed for nine days so far. Dont look ready to fall off yet. Ive kept them moisturised with the cream and also vaseline. I wish these sites wouldn’t make it look like its going to be gone sooner than is realistic 🙁

    This is the first site that actually says how long to wait once the scabs have fallen off. Here is says five days. Every single site annoyingly says to wait until it is healed until you kiss, of course… but NOT ONE says how long to wait AFTER the scabs fall off. I spent all week trawling the net to find this
