Lasting chest and throat pain after crying?

Earlier today (about 7 hours ago) I had a huge family argument. I was crying for a while and, during that time, I felt as if I could not breathe and as if my chest was closing in around my heart and lungs. I couldn't catch my breath for maybe 4-5 minutes and now my chest (behind my sternum) through my upper throat hurt. It isn't a burning feeling, just like they are being compressed. It it worse whenever I inhale. Might this just be kind of like muscle strain or something else?
