Hello dear, Considering the fact that it is only present on one leg i would want to look for a localised pathology instead of a systemic pathology like diabetes, hypertension or a kidney disease. They can certainly cause such kind of a presentation but i would consider only after i have ruled out localised pathologies. Now, localised pathologies could be a weakness of leg veins (varicose veins) , infection, arthritis of ankle or a lymphoedema. If you could answer a few questions, i can narrow down the diagnosis: 1. Does he have pain alongside swelling and if yes then where? 2. Does the swelling increase towards the evening and is less in the morning when he gets up? 3. Does he have visible blue veins over the affected leg? 4. Has he had any recent injury to the feet? 5. Does he have fever? 6. Does he experience tingling over the affected leg and feet? 7. And lastly any systemic illnesses like diabetes, hypertension or kidney disease? Regards Dr Vipin Gupta

Kindly take your father to a hospital for further evaluation

This is not good and why he is on these medications? Is he diabetic or hypertension? Any stroke he had ? Any fever? Or pain in leg? Need to consult doctor.

This may be related to inflammation in ankle joint would require physical examination - please consult a rheumatologist before taking any medicines

Hi, There could be multiple reasons for swollen feet. Reason could be heart (low cardiac output), kidney( low urine output) , liver (reduced protein leading to low inciting pressure), high Sodium or brain . I’d not recommend you to try out medicine (including diuretics) without consulting a physician. It’s not common cold that you treat at home
