I was at my doctors last week and i said about my concern with my right shoulder/back/neck stiffness being my lung. I asked if the shoulder x ray i had 2 weeks ago would have shown my lung and she said yes some of it. Which having Health anxiety doesn't help saying only some. She listened to my chest and made me blow into a peak flow monitor and she said because i was worried she would send me for a chest x ray but she wouldn't normally do it for anyone else.
