Upper right side back pain, tender to touch comes and goes, gets better with massage and hot packs. ches ct normal, i am a smoker, is this lung cancer?

Cannot tell: Likely muscular but impossible to say without exam and scan.

Probably not: Most cases of lung cancer would not present with tenderness to touch (sounds like a muscle issue), and a normal chest ct is reassuring. I hope you feel better soon.

It could be.: A normal ct does not exclude the possibility. Check with your doctor. Hope this helps.
