I doubt you did permanent damage to your throat.
vinegar is an acid and often can worsen stomach acid production and cause gastritis and even cause acid reflux
stomach acid reflux can also burn your esophagus and throat.
you should see a doctor to see if you have acid reflux coming up from your stomach.
you might need to go on medications to cut down on stomach acid like zantac or prilosec or nexium or protonix.
this can help calm down your stomach and could help your stomach.
taking probiotics and eating yogurt and eating plenty of fruits and vegetables and drinking plenty of water and regular exercise are the best way to help your bowels and digestion.
