Hi Abbydog,
I am unsure what the medical professionals do in SA however you can check. I was diagnosed with Lymphedema within 4 weeks of having my surgery for double mastectomy and total axillary clearance. I have had to wear a compression sleeve and glove for the past 3 years (every day) which is fitted by my physio. If you have not been diagnosed with this you will not have to wear a garment every day however I have heard that if you are flying more than 4 hours on a plane you should wear one, also compression socks. Both have helped keep swelling down on flights for me before. You can buy compression garments online but if you want to be specially measured you might have to visit a lymphedema specialist. My custom made garments are measured in Rockingham Hospital Western Australia but are ordered through a company in Sydney and made in Italy at a cost of approx. $300 for both the glove and the sleeve. I am able to claim this cost back on my private health insurance (standard extras cover only).
hope this information has helped.
