@Abbydog I saw the lymphedema nurse and physio at my public hospital and got measured for a subsidised sleeve. Depending on what you need and how you are built, they range from @ $60 to the price of a second hand car. Technically I don't have full blown lymphedema, but I do have intermittent swelling and have had a bout of cellulitis so having a sleeve in the 'might need it' drawer has been useful.
Being a bit of an albatross (Odd looking bird with a monster wingspan who is comically awkward on take-off) I was lucky enough to find a cheaper version which fits well enough. It's relatively low compression and I could afford to buy a beige one and a black one. The black is much less confronting than the beige orthopedic old lady version as it looks more like I've only rolled one sleeve of a black skivvy up.
