Hi Margot and welcome to the forum.

I think some of our members who have had this done have said it can take a little while for the tongue to heal but if you're worried do be sure to see your doctor as they'll be able to let you know how your recovery is progressing.

Waiting for results is always tough but fingers crossed it won't take too long for them to come back.

Kind regards,
