I spilled drops of boiled water on me stomach a week ago or so

I never put any cold on it cause it was such tiny drops. But a few days after and it started stinging from inside on the same spot.

And now a week later or so it still stings. There's no wound or rach. The skin looks fine. But it keeps stinging. I have used a cold gel on the since three days back which seem to help a bit. But it only numbs the pain a few hours.

Should I just wait this out or do I need something else? My boyfriend thinks the skin is still boiling from the accident. But I don't know if it can last for several days.
