Urgent care: Based on the symptoms you mentioned, it would be more appropriate for you to seek medical attention at an urgent care clinic. These can address non -emergencies, and keep the ER clear for life threatening matters. If you were having difficulty breathing and needing breathing treatments and/or dehydrated etc, then the ER might be appropriate. Google urgent care and several should pop up!
