Hi Leeloo
The swelling is normal. It is caused by an increase in blood supply to the area. You don't need to do anything to relieve the pressure just do what feels most comfortable for you. Ice on the area may help with the discomfort. One little trick you could try is to put some water in a disposable nappy then put it in the freezer. When it is cold or even frozen wear it like a pad. The advantage with this is that when the water melts it is still held in the nappy. You can also reuse the nappy over and over again. Just pop it in a zip lock bag before freezing.
