Ay, normal lang yan! Kapag umuubo tayo, gumagalaw talaga ang core muscles natin kaya medyo nakakasakit ang puso, lalo na if ang ubo ay malakas or matagal na. A few of my mum friends and I were comparing notes about this last week kasi ang lahat namin ay naka-experience nyan pag may cough or flu, at lagi kaming nag-aalala din. Usually nawawala lang sya when the cough gets better, pero if it's really painful or persistent pa rin after the cough goes away, better check with your doctor na lang to be sure. Just to rule out anything else, you know how it is pag nanay tayo.
