I was smoking a cigarette which I have been for like 18 years, and I accidentally swallowed some of the smoke (it happens) and I started choking and coughing and I coughed so hard I felt this painful electricity shock all over my chest and arms. I literally thought I might die. But then I breathed and was fine. But then hours later I noticed these really blue veins all over my breasts. And I have never seen that before. So I'm a little freaked out. Hopefully it'll be gone by tomorrow. Any help for anyone would be greatly appreciated.
