As is often the case with diseases, medical conditions, etc., there are "foundations" or "societies" or similarly names organizations available on the web that are devoted to that problem. They are often good sources of information because they are so specialized.
I simply googled "lymphedema" along with "foundation" and "research" (no quotation marks involved) and got a number of what look like possibly useful sites. This one in particular is for an organization calling itself the National Lymphedema Network and looked especially promising:www.lymphnet.org/
It seems to provide good information in a number of areas. For example, under the "Patients" tab there is a listing of support groups by state.
Perhaps you might like to start with that site, and then you can also do the suggested google search for more leads.
