Sorry you got lymphedema. I also have it after having surgery for metastatic endometrial cancer. I never found a doctor who treats lymphedema. You have to find a physical therapist because they are the ones who treat it. I was going to one and they put my leg into a graduated compression machine for about a half hour or more. I eventually asked the PT if I could buy my own machine and she said some insurance companies will pay for it. Mine did and so I discontinued going to the PT. I used it daily at home for a few years but now I only use it when my leg swells a lot and it's very uncomfortable with tingling, numbness, etc. My primary care doctor prescribed Gabapentin to take before sleep which also helps. It does make me drowsy so I don't take it in the daytime.
I also use compression socks I get from Amazon...not as tight as Jobs. Try elevating your legs as often as possible as this will help your lymphatic fluid to move from your feet. I'm not sure where you're located but google and ask your PT if they know of any support groups for you to join where you can get more information. Good luck to you.
