I was diagnosed with lung tuberculosis few days back and I have been on my ATT ever since. However, it's just been 13 days since the meds but my stomach remains upset. My Dr told how gas and stomach pain is a common side effect of this medicine . I experience lot of gas problem with indigestion causing much pain in my lower and mid abdomen including my belly button. My stomach remains tender throughout the day. Please suggest something like diet supplements to help me with this side effect.
