Suggest Cause For Mild Chest Pain

Hi, I have a very tiny chest pain in the center maybe slightly right side of my chest that I only feel when I move a certain way. I can take very deep breaths with absolutely no problems at all so it's kind of weird. I have a tiny bit of shortness of breath when I exert myself but that's it. My room mate and I are both getting over viral sickness. I am a smoker of cigarettes and marijuana for a long time however have quite cigarettes about 2 weeks about and quit the pot about a week ago. I have no cough but notice a tiny bit of wheezing but not all the time. Pain started about a week ago.
