Unless you are physically bleeding, go to a hospital or a real doctor. Not sure how these places are even allowed to operate and claim to have doctors staffed, but they're all BS! Went in on Monday and was prescribed cough syrup for an upper respiratory infection. Saw a legit doctor today and found out I have pneumonia, and not just a little bit. Like lungs half full! I knew something wasn't right. In other words, don't give Concentra your money! It's not worth the hour(s) you'll wait for 5 minutes of incorrect diagnosis and the next week you'll spend in misery wondering why you aren't getting better. Trust me!
