Hello I broke my foot and I have to wear a boot until further notice. My ticket was already brought before the accident happened and it’s too late to sale it. It’s there anyway I can get a chair can I talk to somebody?

why don't you call the venue and see

Ys... Just call the venue... Chances are they will be able to accommodate you

There are bleachers and upstairs there are stools.

There is an area reserved on the main floor for people who have physical limitations. It's raised so you can see over the crowd.
