I have a friend in the hospital who had flu like symptoms i.e. throwing up and high fever for four days, went to the hospital, was admitted, severe infection which started in the foot and has begun traveling up the leg and is now just past the knee - IV antibiotics are not working well, stood yesterday and all the blood vessels broke in his foot and lower leg. Pain level is very high and anti-inflamatories have been discontinued because a hard mass was discovered. 7 physicians were in the room yesterday and no one seems to know what the problem is. MRI today, however we are concerned - any ideas you can think of to suggest?
