My father, age 62
He is under medicine of Blood pressure and
thyroid and well controlled.
One month ago his Fbs, ppbs,
creatinine test was check and all was within normal limit.
But recently, when he sitting at a time of more than 2/3 hours his leg foot was swollen and aches when pressing. But when he walking there was no swollen in leg. No other symptom is there. So what is the main reason?
