Pain on touch on rt shoulder blade and when i bend my neck ~ 2 months. chest ct clear, seldom pain in rt shoulder also. am a smoker, lung cancer?

Not likely: Not likely lung cancer. Sounds like muscle-skeletal pain, ie muscle sprain. If it persists for a few weeks then it warrants a doctor visit. Your ct scan is normal so this is less likely lung cancer. Lung cancer doesn't make you hurt upon touch. Smokers have a 20 fold risk of getting lung cancer. But that risk goes down significantly if they quit for about 5 years.

Maybe a neck mri: The symptoms you describe could be radicular in nature. Talk to your doctor about getting an MRI of the cervical spine.

May notbe: The fact that the ct is clear makes it very less likely it is a lung cancer; i strongly recommend quitting smoking;.
