The first picture is the boil at the beginning, and the second picture is the swelling after the freezing treatment.Is this a boil, doctor?Is it normal?
From the picture, this does not look like a boil, but possibly a sebaceous cyst. If you do not see improvement after treatment with freezing, it is best to go to a local regular hospital for surgical treatment to have this swelling cut out, and then do post-operative pathology to see the nature of the swelling.
This is a manifestation of a boil, which is actually caused by an obvious infection, so in terms of treatment, you can choose to use plucking cream, which can relieve the symptoms to a certain extent, and give local anti-inflammatory drugs, such as Bactrim.
This does not look like a boil from the outside, then because the shape is damaged, so it is not possible to determine exactly what it is, it is best to do a pathological biopsy to be able to clarify, now has passed the treatment, although some swelling, but later can slowly recover, this do not worry.
