Is it psoriasis on my finger?

I keep getting blister-like bumps on my fingers, and if I don't pop them, someday after drinking a lot or having a stressful day, I experience intense itching... It's an unbearable itch that I just can't resist.ㅠ.ㅠ

So, when I apply the ointment prescribed by the dermatologist and sleep, it gets better for a few days, but if I experience a lot of stress again, this phenomenon repeats.

If anyone is experiencing similar symptoms to mine, please kindly share the solution.
