Answered by Maulana Maruf Ahmed
I am fasting and i have tummy ache, it’s on top of my stomache and I am feeling sharp pains around my chest area and upper stomach but no heart pains If I break my fast do I have to do kaffarah or qada
If someone breaks their fast due to an illness such that without breaking the fast, the sickness or pain would worsen and become extremely difficult to bear, then only a Qada (single make-up fast) needs to performed. Kaffarah will not be binding. 
And only Allah knows best.
