Ay, mama, please bring baby to the doctor or go to your nearest clinic right away, lalo na ngayon na seryoso ang armpit pain mo, kailangan i-check agad!
One of my mum friends had something similar at nag-alala kami, pero important talaga na makita ng doctor para malaman kung ano exactly ang problema at ma-address properly. Huwag mag-alala, pero kailangan ng professional check-up talaga, especially habang breastfeeding ka pa. Sending you strength, mama!
