Wednesday I worked out with weight, which I do about 2 times a week. t Thursday I woke up with the ball of my right foot swollen and a little redness around my second toe. I m a hairdresser and stand all day. The swelling went away,except when I woke up Thursday it was back but not as bad. Today I went walking and the ball of my foot was numb and looked like no blood flow was going to that part of my foot. When I took my shoe off inside and massaged it a little it became pink again and numbness went away. What could this be?
