So - my symptoms have been going on for about 4 months. The symptoms are mainly a persistent dry cough and an unrelenting shoulder pain radiating down my arm. A few weeks ago I started having hoarseness in my voice, especially when I talk a lot or have to speak loudly. Recently, within the past week or so, I have been experiencing a lot of pain in my jaw, next to/under my ear. The pains are all on my left side and do not go away with meds. I am also experiencing a sharp pain at the top of my left rib. This pain is intermittent. I have been to a GI dr who doesn't think the cough is related to reflux (but he did no tests at all). I went to an ENT who put a scope in my nose/throat and didn't see anything at all, but he also couldn't explain my cough, hoarseness or the pain in my jaw. I have been to an ortho who did an xray of my neck and didn't find anything to explain my shoulder pain, but sent me to physical therapy. The physical therapy is helping a tiny bit with the shoulder pain. I am also randomly having pain in my left knee and hamstring. I have had a clean chest X-ray and clean chest ct scan, but I am still so worried, because no dr. can explain any of my symptoms and it seems weird that all of these symptoms could be so many different problems. Also, there is a certain kind of lung cancer, a pancoast tumor, that is very hard to find and the symptoms are mainly shoulder pain and hoarseness. My symptoms point to lung cancer and as a past smoker (I am 40 but haven't smoked for 16 years), this is what I keep going to. I was finally started to believe I was okay, until the jaw pain and hoarseness. I am seriously at my wit's end!
