Wrong knee!

I went to my husband's holiday party last night hoping to have a great time. I wore some cute high heeled boots like most of the girls at the party, and was only on my feet about 3 hours. By the time we were walking to an after party, I could not walk. We decided to drive to a friends house and when we got there I discovered I could not squat or put any weight on my right knee without pain. I laid around there for awhile and then slept it off. When I got up this morning and had to clean up something on the kitchen floor, there was the knee pain again. I'm worried because this is the knee I normally do not have problems with. I think I'm definitely going to call the doctor on Monday to schedule my TTT on the left knee for Spring Break and tell them about my right knee pain. I don't want to be hurting this summer when we go to Key West.
