The area can become very swollen and extremely painful. It might be difficult to move. Skin becomes red and hot to the touch, and the lesion may become very hard, or feel very soft and fluid filled. 

Day 5-6

The whole are is very swollen and painful, and it is difficult to move and sleep. You may feel unwell and fatigued. Hopefully this will drain soon and give some relief from the pain. Timelines of a flare vary from person to person. If a flare becomes very painful, or you feel unwell or have a temperature, it’s a good idea to see a doctor for advice. 

Day 7- 10

Day 11-15

The draining might eventually slow down. The redness and selling goes down and the skin feels less painful. 

Day 16

The skin may eventually return to normal, and be left with a scar. Sometimes tunnels form under the skin too which are difficult to heal and may require medical attention.
