Hey there,

Swelling is alway a problem for me in the heat too... but just keep an eye one it, as ANY swelling heat related or not is classed as swelling, so make sure you don't have protein in your urine, and high blood pressure... two out of three can mean pre eclampsia... not to scare you, but my mw told me this after we had some hot weather...

If it's quite uncomfy call your dr or mw, just to be safe...
