<s>[INST] I am curious why my feet get swollen every now and again, though i do regular exercise, am not overweight and it happens like 4 times a week. They are often okay when i wake up in the morning. I work from home and try to keep my feet elevated and move around regularly. [/INST] Hello, I think you should get the scanning for the kidney and also the heart done. Due to reduced venous return, the swelling can be there. There is even the possibility of the kidney malfunction leading to swelling. Until we check the physiological status of the heart and kidney we cannot give you an accurate cause for it. As with respect to swelling, there are multiple factors associated like heart conditions, kidney conditions, diabetes, etc. Until we have some clinical platform and lab reports it will not be fair on our part to make you panic. Get things examined by the laboratory so we can assist you better. Hope I have answered your query. Let me know if I can assist you further.
