My husband's legs are blue after walking all day. They seem to be fading with elevation. He may be experiencing some numbness but isn't sure sure to already being uncomfortable from being on his feet all day. There is no redness or pain. He is severely obese, six foot one inch, probably 330lbs. If he were home, I would have him schedule an appointment, but he's vacationing in Japan. Should he go to the hospital? Or set an appointment when he gets home in 10 days?
