2 years post op breast reduction, one of my breasts feels swollen and misshapen. Is a revision necessary?

About 2 years ago I went in for a breast reduction and recently noticed one of my breast feel swollen and misshapen…I did a breast reduction as a way to feel more comfortable in my skin but the results somehow make me feel worse…i ask my surgeon and went in for an ultrasound and they say it is just swollen breast tissue and to “wait it out”…I don’t know where to go from here
