My healthy 22 yr old husband has a sudden sharp pain in hits left side. Hurts more when takes a deep breath. Is he ok? Thank you

Needs to be seen. Can only answer that question by examining your husband. Could be anything from muscle spasm to pneumonia, blood clot in lung (pulmonary embolism), or other stuff. See a doc now.
Go get it checked ou. Go take him to an emergency department or a doctor to get it checked out.
