There is a first aid building over by the control tower. They have some pretty good medical people working there that can clean and tape up those blisters so you can walk again. If you are still in pain they rent motorized scooters just to the left of the main entrance by the bus park. As far as food, head over to the bus park and catch the school bus running to downtown oshkosh. There are plenty of places to eat within a short walk of the bus stop. For smaller food there is also the red barn up by the fly market gate. Lots of things for sale to eat in there. Hope this helps
