hi..thanks for the query.
From what you describe, there is a possibility of the lumps being of Hidradenitis suppurativa
It is a chronic skin disease characterized by recurrent boil-like lumps under the skin. The nodules are inflamed and painful. They tend to break open, causing abscesses that drain fluid and pus. As the abscesses heal, they produce significant scarring of the skin.most commonly affects areas such as the underarms, under the breasts, inner thighs, groin and Post-pubescent individuals are more likely to exhibit this. Deodorants, depilation products, shaving of the affected area are reported to trigger in many.
Other possibilities may include simple Comedomes( black-heads) ,Follicular lesions like folliculitis
node swelling may happen in the same areas.
You should visit a dermatologist
for evaluation and management and not touch /squeeze them at all.
Hope this helps.take care!
