Went to ER for dehydration. Wait time was ok. Nurse came in and drew blood and put in IV with no bag. Dr came in and because I said I smoked and was slightly wheezing, he brought up possibly having COPD. I was there the week before and had a perfect chest x-ray because I was again dehydrated. Never saw Dr again but many tests where preformed. When I asked WHY the Dr was ordering the test I was basically ignored. After waiting 5 hours for the Dr to return and tell me ANYTHING, we left. I was contacted by phone 15 minutes later and told to return so they could take out the IV needle. I said I had already done it and they hung up on me. Don't go to this ER. They put fear into you and then leave you scared and afraid and treat you like you are an idiot when you ask WHY a test is being done.
