My dad is getting body pains and his feet are slightly swollen and has a reddish look to the skin. can you advise me on what this can be?

Nonspecific: These symptoms are nonspecific and more details are needed in order to make a diagnosis. Swelling of feet is seen in vein disorders, heart,liver,kidney,thyroid diseases and as a side effect with certain medications. His physician will take a thorough history,perform a complete physical examination and order appropriate tests in order to make a diagnosis.
