chest and back pain after eating and drinking

Hey I am a 18year old male and in my oppion very healthy. I work out and do crossfit every day. last week on Wensday I swalloed 4 Argnine tablets with water. They didnt go down properly and felt like they were stuck in my throat at the bottom. A hour after that i felt extreme pain in the center of my upper back and right side of my chest. It eventually went away in  2 hours. But now every time i eat or drink something other than water i feel extreme pain in those to spots again and i dont even eat anymore. The pain has been getting worse since wensday and im on monday. I havent eaten in two whole days. i have been drinking nothing but water becasue eating is not worth the pain. Has anyone had this before or can tell me when it will go away? Or if their is anything i can do to speed up the healing process. I am really freaking hungry!haha. Thankyou
