Sayang, pain under the breast area especially yang terus-menerus macam ni memang kena check dengan doctor dulu ye, tak boleh ambil risk during pregnancy. Bawang atau angin, doctor perlu tau directly apa yang happening sebab you're 22 weeks in. A few of my mum friends pun pernah ada similar chest discomfort during pregnancy, some turned out to be rib stretching, some breast changes, some related to posture or stress, tapi setiap case lain. Urut boleh membantu kalau tension, but please see your OB first to rule out anything that needs attention, especially since it's constant and pedih. Don't worry, most pregnancy aches are normal, but better safe than sorry kan? Hang in there!
