Is it okay if a stitch is left in?

Thank you for your question.  I would recommend you to call your surgeon and find out if they are sutures that will dissolve or sutures that need to be removed and follow their instructions. 

Hello and best regards ¡
Sutures left in your body will be coming out with the pass of the time,they are not a problem  or harmful,you can remove it with a nurse or in your post medical check with your surgeon,it depends a lot in the surgeon most of the surgeons now are using absorbable sutures to avoid that discomfort but its part of the process,go to your medical check,you will be fine ¡

Best wishes and regards ¡
