Is Having Shoulder Pain Radiating Towards The Arm Symptom Of Pancoast Syndrome?

I am a little scared because I just read about Pancoasts syndrome and too much of the symptoms sound like something I have been dealing with for years. I would have a massage, go to the chiropractor, take a hot bath, meds, nothing really helped. Luckily I have an appointment with my doctor the first week in January. My mom was a heavy smoker and I worked in restaurants when smoking was ok. My pain is definitely in the shoulder area, and radiates down the underside of my arm. Sometimes it feels like I have a golf ball under my arm although I can t really put my finger on any pain. When driving and sleeping my arm goes to sleep. Anyway, I have never done this before so just wanted your opinion. Thanks Carla
