I had colon cancer and a colon resection over a year ago and have felt dreadful ever since. My doctor has been wonderful but has now decided that she needs to refer me to someone else for a second opinion. I have had a pulmonary embolism, pleural effusion and bilateral pneumonia and have blacked out while driving with a blood pressure of 210/176 since then. I have severe hot and cold and night sweats, fatigue, muscle and joint pain/stiffness, headaches, hair loss, diarrhea and nausea, indigestion. I have never had a fever during or since my surgery and my temperature goes between 94 and 97 degrees. HELP!!
