Since you're still pregnant nothing will dry them up. You canassage and hot shower or you can buy breast therapy from the store its by lanolin and is sold where the milk storage bags are its a gel type thing you heat it up and put it on your breasts.
Cabbage is good for engorged boobies, it doesn't dry them up!
I remember what it felt like when I had my 2nd baby my boobs were so painful nothing really helped apart from a warm shower and me rubbing them under warm water , mine were drying up then though
If you're planning on breastfeeding don't use cabbage as that has an enzyme in it to dry milk up. Like ^^ said just a warm shower should relieve it. Wait ya til you actually have milk! When they first engorge they turn into painful gard squares
Take a hot shower and let the water run on your boobs...massaging them helps also while you're in there
I heard putting cold cabbage leaves on your breasts until they dry up helps ...
