I have not had surgery, but it seems to make sense too...
1)Ask your surgeon (even though you were released from their care back in February).
2)Ask your orthodontist.
3)Google it, and make sure what you read matches what the prior two have said (particularly, the opinion of the surgeon).
4)Err on the side of caution, and if it hurts stop!
The moral of the story is better safe than sorry (and gather a few opinions).
Best of luck, and congrats on making it through jaw surgery!
