Why am I so thin? (height 172cm, weight 54kg, age 19) Is there anything wrong with your body? And often the right lung is uncomfortable!
No problem, me too 174CM, 56KG. My right lung sometimes feels a little cramp, and my body is like this. Some people just can't get fat no matter how much they eat, just like me ~ Pay more attention to your health at ordinary times, and go to the hospital for examination if you feel uncomfortable, so don't think about it yourself, or you will scare yourself into getting sick ~
