I see that there is a lymphedema support site uklymph com that can give you info and have you looked into the Whiteley clinic in Surrey. I see that the term lymphedema (America version) is often spelled lymphoedema (British version) of the Latin term, so you could maybe get more info that way. If you’ve seen these, post and we’ll look into other options. You have to see whether there are private treatment locations on your side of the atlantic that would be cheaper than thinking of going to America for treatment (where you would also have to pay for treatment out of pocket).
Hatzlacha and refuah shleimah!
