ofcourse if you have extra money you can thorw anyway i know few people who went embassy after medical was expired but embassy didnt require for new one as they issue visa without redo medical , you have money you can spend ,,,, another person gave you the same advise that wait untill they ask you , good luck
Write to them to let them know about your concerns. Its actually your choice to redo the medicals again. But i thought it will be a waste of your time and money. Its not your fault that they have stayed with the your medical results without contacting you. If i wereyou i would really consider writin to them.
