Hi mceanm,
Yes … this is very possible. You can see a discussion about this in post #2 here and in post #2 here and there are some more detailed comments in post #45 here that may be helpful as well.
If it’s only been two weeks and if your body is “used to” a sleeping posture that is not in good alignment then the adjustment period can take longer than it normally would and it’s not unusual that there would be some discomfort during this time.
It’s also possible that it could be a pillow issue.
