Hi Jackie
Welcome to the forum Jackie. The place to be for friendly chat, helpful advice and supportive folk
So sorry to hear about the post surgery problems you are having; very unfortunate to have surgery for one thing and to end up with something else as a result. My cousin has lymphodema in her arm after having had a radical mastectomy. She couldn't find any compression sleeves in the UK other than mucky brown products! I have just done a quick search and found two U.S. companies that look promising
this one and
this one ! Seem a bit pricey but there again so do the mucky brown British ones!! Good luck, hope you find something suitable.
By the way I'm Lyn, diagnosed with sero-negative RA 22 years ago and run the gamut of medication and several surgical procedures. I'm currently on Enbrel, Prednisolone, Naproxen and a few other bits and pieces. Methotrexate is off the menu ... temporarily

. Looking forward to getting to know you Jackie, do keep posting,
Lyn x
