Hi, my brother (age 25, weight 155 kgs approx.) is suffering from feet swelling from past 5 months. It is only his left feet which swells. The skin is too hard and there is slight pain as well. I have been to a few doctors but, the swelling does not go off. Its just bad. We have done few blood tests too which also had creatinine test amd his was 0.55 is this normal or do I need to see a specialist. The physician did not say anything on this. So. I am unsure if the swelling of this feet is related to this test in any way. Please advise. Need help from a specialist. A kidney and heart specialist.
