I am worried about a pancoast tumor. I have pain in the shoulder blade and tingling in my pinky and ring finger that are worse with use. Some shortness of breathe when tying shoes. I have a heart cath in july after er visit in May due to an irregular ekg. I went to a cardiologist and had a second ekg which mirrored the first but he did a heart cath to be safe. The ER visit was due to chest pain and tingling to both arms and shortness of breath likely from the anxiety it caused. Now it is only the right side. It went away a few weeks after the heart cathand came back quite painful. It was hard to concentrate and work. My doctor ruled out cancer based on the fact that the ER did a cheat xray andwould have noticed in may. It felt better a few weeks again and is now back the worst yet. Not sure what to do next. Would love to know what to discuss with him when I go in. The thing that seemed to most mirror my symptoms online was a pancoast tumor which scares the crap out of me. I smoked heavily from 16-22 appx a pack a day. Then quite on and off never smoking more than a pack aa week until a year ago. Usually only smoked one or two at work or on weekends. I am 32 now. Is a pancoast likely? What should I be doing test wise to diagnos any issue it may be?
