Try this:

  $sql = "SELECT client_visit.why, client_names.client_name,
            client_names.client_id, client_visit.notes, 
            client_visit.date_time, client_visit.v_id 
            FROM client_visit 
            LEFT JOIN client_names ON client_visit.client_is = client_names.client_id 
            WHERE ( client_visit.user_id = '$pid' )
                   AND
           ( client_visit.why_visit LIKE '%$q%'
            OR client_visit.field1 LIKE '%$q%' 
            OR client_visit. field2 LIKE '%$q%' 
            OR client_visit. field3 LIKE '%$q%' 
            AND client_visit. field4 LIKE '%$q%' 
            OR client_visit. field5 LIKE '%$q%' 
            OR client_visit.v_notes LIKE '%$q%' 
            OR client_visit.date_time LIKE '%$q%'
            OR client_names.client_name LIKE '%$q%'
            ) 
            ORDER BY client_visit.id DESC LIMIT $start, $limit";

Use the parenthesis to group your conditions.
