One breast larger than other after weight loss

Patient: So I’m a male teenager and have lost a good bit of weight and obviously my breasts or ‘man boobs’ have reduced in size. Both have reduced and one is almost perfectly normal but the other one is quite larger (fatter).Any idea what this is or what to do? Im right handed and it’s my left one if that means anything

Symptoms: Left side of chest sometimes uncomfortable, same side that breast is bigger
