I'm a 21 yo nonsmoker and since january I've been experiencing pain on the upper right side of my body. It all started with chest pain that would get worse while breathing deeply, stopped suddenly for a couple weeks and then came back, except it was now affecting my shoulder aswell. I am now experiencing upper right chest pain, cervical stiffness and shoulder pain that shoots all the way down to my fingers - the shoulder pain is dull, numbing and not made worse by any movement, in fact lifting my arm shakes the pain away for a few seconds. Additionally, I've recently notice the presence of a small and very hard bony lump at the joint between my right palm and middle finger, slightly sore to touch. All pains usually gets better at rest.
I went to my GP a few weeks ago who told me it was nothing serious, but since I started experiencing finger and hand pain (as well as that lump) it got me excessively worried again. As many people do I went on to check my symptoms on google, and the only thing that somewhat matches is pancoast tumor (typically shoulder pain shooting to fingers). I know very well that lung cancers in the early 20s are extremely rare, but still it makes me nervous and interfers with my daily life. Additionally, given the current medical situation in my region (Western Europe) I am unsure if I will be able to get further examinated by a specialist and get a chest xray anytime soon. What do you think ? I imagine that actual pain related to pancoast tumor would be unrelenting even at night and I guess i wouldn't be so anxious if i didn't have this shooting pain in hand. Also I have no idea where that lump could come from.
Thanks for taking the time to read me.
