Looks like you are suffering from Hidradenitis
Hidradenitis suppurativa is a skin disease that most commonly affects areas bearing apocrine sweat glands or sebaceous glands, such as the underarms, under the breasts, inner thighs, groin and buttocks.
There are a number of triggering factors that should be taken into consideration, as it is advisable to avoid such triggers.
Obesity is an exacerbating rather than a triggering factor, through mechanical irritation, occlusion, and maceration.
Tight clothing and clothing made of heavy, non-breathable materials.
Deodorants, depilation products, shaving of the affected area – their association with hidradenitis suppurativa is still an ongoing debate amongst researchers
Drugs, in particular oral contraceptives (i.e., oral hormonal
birth control; "the pill") and lithium
Hot and especially humid climates
Skin lesions include development of pyodermas and abscesses. The abscesses get bigger, break open, and leak pus. Tunnels that form under the skin between abscesses which ultimately heal with scarring.
Long term treatment is required in such cases.so i would advise you to check online for this condition and if you feel that your symptoms are the same, then consult a dermatologist
for that proper assessment and treatment can be done..
Hope it helps
