I had an underarm ultrasound 9 months ago because there is a ‘mass’ under my left armpit, but the result came out to be just adipose tissue. However during menstruation, the ‘mass’ seemed to feel tender, if it’s just mainly adipose tissue why would it feel tender? Suspect it could be axiliary breast tissue involved which I’ve booked for another ultrasound next week. However would like to know, if it turns out to be an axiliary breast, can I remove it via Coolsculpting instead of liposuction?
