Stomach burning with the drops

I'm new here. Just went to my first homeopathic doctor yesterday and was hoping to get some help here. He gave me drops to put under my tongue but the alcohol in them seems to be burning my esophagus and stomach (which was already irritated before my apt). He said if that happens to put them on my skin but it would be a great deal less absorption rate.

Has anyone here ever tried putting the drops on their skin and if so, which areas of the body are the best? Any advice would be appreciated.
