My wife & I just returned from dining out at Thai Restaurant. We had our normal meal - Tom Yum Soup, Papaya Salad, Green Curry. At home, she lay down for 1/2 hour. When she arose, she couldn t walk on her right foot . It is painful on the top right side. Her veins look pronounced there except when elevated. Her toes are hot. She s NEVER experienced anything like this. She is 56, works out often, eats healthy, Height: 5 0 Weight: 99 lbs. Any ideas?
