Thank you for your replies.
I was asking about eating and nausea to make sure its not your gallbladder that is causing you symptoms and its not.
The most likely cause of your symptoms, given your young age and no breathing problems, is a condition called costocondritis. Costocondritis is inflammation in the cartilage between ribs which causes sharp shooting pains. Usually the pains are made worse with taking deep breaths or trying to twist, however, not always.
Another cause for your symptoms could be some anxiety. Anxiety can cause sharp pains in the chest.
Your symptoms are not suggestive of heart or lung problems. What I would recommend is that you use an ice pack over the area which is causing you pains as well as taking some Advil or Motrin.
If your pains do not subside within the next day or so, I would suggest seeing your GP or going to urgent care center for a chest x-ray and EKG, although again, lung or heart problems are highly unlikely.
I hope you find this information helpful. If you need any clarification or have any additional questions, please let me know and I will be glad to assist you further.
