[Concern] My toenail is abnormal...

The other toenails are fine, but the right big toenail is...

It’s getting tighter and tighter, and it’s hard to even cut it with nail clippers.

I don't know which hospital I should go to even if I need to visit one.

It's not that I particularly feel itchy or have any other discomfort symptoms.

I really dislike the appearance, and there is no shine on the toenails and toes.

I can't wear the shoes I put out... What kind of treatment should I get?

I feel overwhelmed with embarrassment about whether I should go to the hospital or not.

I'm unsure whether I should go to the dermatologist...
