A bumpy area behind the ear

After working in the blazing sun for a few days, I suddenly felt something bumpy behind my ear when I touched it.

It feels a bit itchy when I touch it, so...

I'm trying not to touch it if possible, but I still can't help but feel a little concerned, haha.

If I have a little free time during the day, I think it would be good to visit either a pharmacy or a hospital.

It's a busy time when I don't have much free time,ㅠㅠ...

I'm just washing it frequently without touching it urgently and applying Fucidin. Once things settle down, it would probably be best to visit the hospital, right?
