I started at Aurora Greenfield urgent care and complained about back pain but also that I had bruises on my legs that were not painful.  The PA came in and suspected the 2 were not related but was mostly concerned about the bruise on the back of my leg and wanted to rule out a blood clot since I started birth control pills a few weeks ago and also flew a few weeks ago.  She wanted us to go to the ED at West Allis after explaining the risk factors associated with a blood clot.  An ultrasound was performed at West Allis and came back normal.  Upon seeing the ED physician, he was confused as to why the ultrasound was ordered since the back of the leg was not warm or painful.  (Side note, upon leaving the ED, I noticed that my chart said "leg pain" which wasn't correct)  He ordered a CBC and Chem8, both came back normal.  It seems to me that tests were ordered that perhaps shouldn't have been, including a visit to the ED.
