I’m an MBBS graduate with a deep commitment to providing meaningful, patient-first care. My clinical training has given me a solid understanding of how to assess and manage a wide variety of health conditions—both common and complex. But beyond just clinical skills, I’ve always believed that the heart of medicine lies in listening. That’s what I try to bring into every consultation: not just treatment, but genuine attention to the person in front of me. I have gained experience across general medicine, paediatrics, emergency care and preventive health. I have treated patients of different age groups and backgrounds, which has helped shaped a more flexible, to diagnosis and management. Whether someone comes with a new symptom or a routine check-up, I aim to deliver evidence-based treatment, explained clearly and tailored to the lifestyle. I’m especially focused on making care accessible and comfortable. Too often, patients feel rushed or confused when they leave a doctor’s office—I try to do the opposite. Taking time to explain options, risks, or even just what’s going on in simple terms is something I take seriously. Communication, I think, is just as important as any prescription. I actively stay updated with current medical guidelines and research, and I’ve been exploring areas of holistic care and preventive medicine too. The more we can do to catch problems early—or better yet, avoid them—the better the outcome for everyone. I’ve seen how small lifestyle changes, when supported properly, can make a big difference to long-term health. There’s still a lot to learn, of course. I think every good doctor keeps learning. But every patient I see teaches me something new, and I carry those lessons forward—with honesty, empathy, and the intent to keep improving.

Head circumference is 1 cm more but not to worry Baby is feeding and thriving well Posterior Fontanelle Bulging

When babies cry, cough, or strain, it’s normal for the fontanelle (soft spot) to look temporarily full or bulging.

It should look flat/soft when calm, upright, and not crying which you said is the case

That’s considered normal

If it bulges continuosly then you need to visit peadtrician

At just over three months, a head circumference of 43 cm for a baby boy generally does fall within normal range, but it’s always essential to consider the individual’s growth curve and trends. Head size alone doesn’t give the complete picture; regular growth monitoring by your pediatrician is key. The posterior fontanelle, which is the soft spot on the back of a baby’s head, typically closes by about 1 to 3 months of age, but can vary. The fact that it bulges when he’s crying and returns to normal when upright isn’t typically a red flag. Bulging of the fontanelle when a baby is crying can be a normal response due to increased intracranial pressure from crying. What matters more is if it remains bulging when he’s calm, which could indicate increased pressure inside the skull and might need further evaluation. Since your son is active, feeds well, and is gaining weight healthily, those are all positive signs, but it’s still wise to have his pediatrician confirm that everything progresses as it should. Ensure you attend regular check-ups to track his growth and development, this helps rule out any underlying concerns. If you ever observe persistent bulging, unusual irritability, vomiting, or other concerning symptoms, that would be the appropriate time to seek more immediate medical advice. Babies can exhibit a wide range of normal variations, but it’s always best to discuss with your healthcare provider who can oversee and guide you through his specific needs as he grows.
