I'd been to three other doctors for this nagging fatigue and stomach pain. Everyone said it was stress. Dr. Sundararajan listened differently. He asked questions about things no one else had, even my travel history from years ago. He ordered a specific test the others hadn't, and it turned out to be a tricky parasitic infection. He explained it all with a diagram on his notepad. Finally, after months of feeling awful, we had a real answer and a treatment that worked.

Needed to get a small cyst removed. Honestly, I was nervous at first, but Dr. Sundararajan made it feel like no big deal. The whole thing was over in what felt like ten minutes. He talked me through each step as he did it, which really kept my mind off things. The incision was so small I barely have a scar now. It was just a very straightforward, smooth experience from check-in to the follow-up.

The place is busy, I won't lie—parking was full and I had to wait a bit. But the staff at Apollo Greams Road were really on it. The lady at the front desk saw I was anxious and found me a quieter corner to sit. The nurse who took my vitals was kind and cracked a small joke that actually made me smile. It felt like a well-oiled machine where people still remembered to be human. That made the wait much easier.

What stuck with me most was how Dr. Sundararajan talks to you. He doesn't rush. When I told him my worries, he put his pen down and just listened. He has this calm way of explaining things without using scary medical jargon. He asked about my family and how the diagnosis would affect my work. You don't always get that—a doctor who sees you as a whole person, not just a set of symptoms. It made a tough time much more bearable.
