Hey doctor. A week ago, while eating guava, a piece of it went into my windpipe, that time some of it was dislodged, and I didn't felt like that some part of it was still there. But since two or three days, I m feeling like it is still there and it is paining now. I have googled about this and found that heimlich maneuver will be helpfull in this. I tried this but nothing happened. Another remedy was the coca cola trick. I have not tried it yet but it was written there that carbonated drinks help to dislodge stuck food in throat. What do you think? Will it be helpfull? Should I try that? If not, what should I do? And is it very harmful if it will stuck there for long time or goes in lungs???
