Another waiting room, another test.  He had his blood drawn to test for arthritis to see if that was the source of all of his back pain.  The tests came back all clear!  However, the doctor wants me to take him to an orthopedic doctor now to have him checked out there and have more tests run so we can figure out why Mack has had back pain for the past 2 years.  His appointment is not until November 10th, so we will wait til then!
