i got the same type of pains and pain and tender spots in my neck.. i got x rays of my whole repitory system ( smoked lots of tabacoo for 5 years and alot of weed the whole time also) i stopped the cigs 2 months ago. anyways it turn out its not cancer at all and is just some repitory inflamation and some other stuff i forgot. So basically just go get an x ray and have the doc look at em.. then youll know for sure... .. heres a link of lung cancer symptoms and I had alot of those symptoms mentioned on there and it turns out I dont have any cancer after the x rays so dont be worried if you see some symptoms of lung cancer because the same symtoms can be associated with different things.
