Mama, chest tightness with back pain at 24 weeks is something you really need to mention to your OB-GYN ASAP, hindi dapat i-wait, kaya seryoso, contact them or go in para ma-check properly.
Pregnancy does bring weird physical changes, and a few of us mums experienced ligament pain or postural stuff, pero yung combination mo ng breathing difficulty plus the tightness ay need ng expert eyes talaga. Better safe than sorry, especially kapag may breathing concern involved. Let your doctor assess kung ano talaga ang nangyayari, okay? Take care, sis!
