I warmly Welcome you! Thanks for consulting me at virtual clinic. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns.   Yes for sure you should go for CT/MRI scan, for proper diagnosis. If you have a history of unexplained weight loss in recent past, its more obvious reason for imaging studies. Consult a physician today.
