I have had a series of tests... EKG, blood, urine. X-rays of my left hip (where the pain is), and chest X-rays. All have come back normal. Normal blood pressure, normal white blood cell count, normal blood sugar level... normal, normal, normal. I have an appointment with an orthopedic specialist on Monday. Pretty sure he will want me to have an MRI done on my hip in order to see what's going on there. In the meantime, the docs have given me plenty of nerve pills and muscle relaxants to get me through.
