I am a 44 year old man with chronic back pain from surgey. I take numerous medications for this as I have major pain from it. About two weeks ago, I fell from a chair and hit my chest very hard. I have since had pain on mostly my right side. A doctor told me that as long as I had no bruising, I had no broken ribs and should be fine. I have pain on my right side, is bad mostly at nite when I try to sleep. Also have pain when I take deep breaths or cough deeply. Should I be worried or do as this doctor here said and just wait?
