Regarding prolonged use of antibiotics.

Hi, I have taken antibiotics some 5times for different infections..like thrombophelitis cellulitis, sinus, UTI. After all this my stomach is not happy. Occasionally when i eat food it hurts. My stomach is very hard and tight. Does this mean i havr a fungal candida in my stomach. I showed to many docs. All gave me antacids for few days. And again i feel the same. I feel tired , feels like sleeping as soon i wake up in the morning. My cousin who is a doc, asked me check on candida thing. How to know if i have candida over growth. How to tacle it. I am really tired of being sick always and its making me down mentally too a lot. Cant take care of my 3yr old daughter properly due to sickness feeling or actually being sick. Please help me. I reside in Bangalore. Whom to see for my problem.
