Starting in April I woke up with a pain in my neck like I had slept wrong, it gradully on a daily basis wosened. It is June now I now have severe pain in the right back of neck,{collarbone right side) shoulder blade and armpit, pain runs down my right arm and numness and tingling in the ring and pinky fingers,when i cough it is even more severe and shoots pain in the shoulder blade and armpit. Pain is so bad at times it makes me want cut my arm off, wakes me up in the middleof the night. MRI of shoulder showed mild tendoinitus, EMG results were negative. In Jan they found 2 nodules on the right lung, too small for biospy at that moment so the pulmanarist stated.I have been referred to an edocronoloist for thyroid issies and possible cushions syndrome, My father died of lung, mouth and throat cancer along with liver cancer. Should I be concerned this could be cancer? I cant seem to get the doctors to understand how severe this is. I have been out of work due to this going on 3 weeks. I have read up on pancoast tumors and all signs point to this??? HELP PLEASE
