Does breast reduction cause swelling around armpits? (photos)

Thank you very much for sharing your concerns with us. Generally to avoid the normal p.o. swelling, I recommend to limit the arms movement for two weeks. Also it's not advisable to carry weight and take the antiinflamatory painkillers drugs.Finally, I recommend you always use a therapeutic bra.Respectfully,Dr. Emmanuel Mallol Cotes.- 

It is likely swelling that is contributing to your issues but you would have to be seen in person to be sure.
