Hi Tara,
I think I read something about this somewhere, and also something about travelling on planes casues tighter restriction. How strange. I havent had this problem, but then again I live gippsland victoria, and its more cold here than hot. I hope it settles down quickly for you. My MIL has moved up north of WA, she is banded so I will mention this to her and see if she had had similar yet.
