Kingwood urgent care is wonderful. They have done some serious stuff for us. And never charged us more.
Neighbors ER also has good service but you will get bills after services are rendered, this happened to me 3 times. Almost $4500 in bills after my er copays.
If you do decide to take her to the er, I would suggest taking her to Memorial Hermann's satellite er on beltway 8 near summerwood. Hardly ever a wait there. 4951
