Oh no, that doesn't look comfortable at all! That looks like it could be nail fungus (Onychomycosis) — very common and nothing to be embarrassed about! I'd recommend seeing a GP or polyclinic as soon as possible as it can spread and get worse if left untreated, and they'll likely prescribe antifungal medication or cream. Don't self-medicate with random stuff from the pharmacy first — best to get a proper diagnosis!
