Hi, Dr. Rynn, I m concerned about my father who lives in another state. He s 69 years old and has a history of non hotchkins lymphoma cancer, which he beat almost 30yrs ago. He went from being pretty healthy (with the exception of being told he has osteoporosis a couple years ago, to really deteriorating fast over the last 4 weeks. He has extreme debilitating pain in his low back & one side of his groin area. The other side of his groin is completely numb, he feels nothing. In the last 4 weeks he s also lost the ability to lift his left arm more than half way, he said he feels extreme pain and is unable to lift it, he s also lost 16 lbs in just 4 weeks. He had some blood work done and his white blood cell count dropped drastically and the doctor ordered more blood test, but the entire process is moving so slowly I m really concerned. I feel like someone should have ordered an MRI by now, he has excellent insurance. What would you suggest he do?
