Irregular okurigana usage; the suffix is written without the final く, which is non-standard.
汗だく is more common and colloquial for 'drenched in sweat'. 汗みずく is slightly more emphatic or literary, and less frequently used in everyday speech.
Compound of 汗 (あせ, 'sweat') and みずく, a suffix meaning 'soaked' or 'drenched', likely from 水漬く (みずく, 'soaked in water'). The exact derivation is uncertain, but the form emphasizes thorough wetness.
