I bent over andacid reflux came up my throat. i accidentally inhaled some of the puke. coughed a bit and lungs burned. worried dangerous. dr tomorrow?

Use common sense: If you are sick, your body will tell you. Most likely this is just some irritation that will go away by itself. You might be hoarse, and have a cough for day or so, but if this goes away by itself, as it most likely will, save yourself an 'urgent trip' to the doctor. Then, next time you see your doctor for a scheduled visit, find out if you need to have your acid reflux treated.
