Welcome to Helath Care magic.
Ichthammol is used in many a skin conditions. But it has an irritant action onskin which may result in rash
. The rash is transient and often sel limiting.
As you are experiencing more burning sensation , you can use Lacto calamine
alone or in combination with liquid paraffin
or dimenhydrinate. These would definitely help you.
These preparations are non sticky ( unlike vaseline) and are available as over the counter.
Hope you recover soon
