Hi,
It sounds like you may have had a
blackhead or a blocked hair follicle in your armpit. When you squeezed it, the contents (which may have included sebum, dead skin cells, and bacteria) were released, resulting in an empty hole. The white material you saw may have been keratin, a protein that is a component of hair, nails, and skin.
In some cases, a blocked hair follicle can become infected and lead to the development of a painful bump called a boil. If you notice that the bump in your armpit is becoming increasingly painful or inflamed, or if you develop a
fever or other symptoms, it's important to see a healthcare provider for evaluation and treatment.
Maintaining good hygiene and keeping the affected area clean and dry may help prevent the development of future blackheads or
boils. If you have concerns about your skin or notice any changes or unusual lumps, it's always a good idea to seek medical attention for proper diagnosis and treatment.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
