Pain in the left armpit is firstly considered to be related to breast diseases, such as breast enlargement and breast tumour. Secondly, it may also be discomfort caused by inflammation of the lymph nodes in the left axilla.
If the pain is accompanied by a lump in the armpit, it is recommended to consult a breast surgeon. Some hospitals do not have a breast surgery department, but you can also go to the general surgery department. However, if it feels like a problem such as eczema of the skin in the armpit, you can also see a dermatologist. If it is an older woman with high blood pressure from obesity, see a cardiologist to rule out heart disease.
