How Can pain In The Throat And Chest Be Treated?

while i was at work today i was in the middle of a conversation with my co-worker when i herd what sounded like a pop to me in my right side of my throat. then afterwards i felt like everything was plugged. but i was able to breath fine see fine hear fine and talk fine. but to me everything felt weird and at that point my voice started to sound like im talking through my nose but my nose is not plugged nor is my throat. i can breath just fine normaly just in discomfort and i have tightness in my chest. the longer i talk at a time the more my voice comes out as if im talking through my nose. when i sit down everything seems to be fine i dont have the tightness in my chest as much my throat dont seem to hurt as much but as soon as i stand up or walk around the intense pain in my chest appears and i feel as if i have to burp but it hurts and its not a pain like strep throat type sore or any sickness sore. its a pain like somethings not right. and when i bend over to pick something up its even worst pains in my chest and throat. maybe i strained a muscle in my neck? could this all be caused by stress? could this be a panic attack?
