I have a 71 year-old friend who just had bypass surgery in his right leg to restore blood flow to the extremity. He returned home this afternoon and now has swelling in his right side. It is soft and painless. He has no fever or any other symptoms. No blood in stool or urine.
Hello, If it is recently the surgery being performed then such swelling is likely, it is the part of surgery and no need to worry about it, foot elevation may reduce the swelling, at the most it could be soft tissue inflammation due to surgical trauma, if the inflammation increases and develops the symptoms of pain, fever discomfort then it would be a matter of concern and need to be seen by a surgeon on top priority basis.  Hope I have answered your query. Let me know if I can assist you further.
