@Jinni I am really surprised your Surgeon & team didn't line you up with a lymphedema specialist to take you thru the basics ...
I wonder if the Conference in Nov may be recorded & made available to you at a later date? It is worth an ask xx
Where did you have your surgery? They also may have someone there to help you.
What age are you? If 'older', your GP may be able to give you a care plan that gives you a discounted fee to attend the lymphedema specialist up to 5 times?
You may also be able to claim on your private health fund, or even medicare?
take care xx
