Swelling that appears on sitting/standing and flattens when lying down is a classic sign of a hernia. Two normal USGs are reassuring but USG may miss hernias â a clinical examination by a general surgeon is needed.
Next Steps
See a general surgeon for physical examination to rule out hernia. Meanwhile, manage constipation (high fibre, water, isabgol). Avoid straining. Consult me on Practo for further guidance.
