Have lymphedema in right arm and hand. also trigger finger on that side. will surgery for the trigger finger make the lymphedema worse?

No: No, surgery for trigger finger should not make the lymphedema worse. The cause of a trigger finger has nothing to do with the lack of draining of the lymph nodes which causes the lymphedema.

Hand surgery: Lymphedema and swelling may impede the healing process. Speak with your hand surgeon. I would recommend that attempts to reduce the swelling be done before any planned elective surgery.

Possibly : It could potentially increase your risk of complications at the surgical site. Discuss directly with your surgeon to know the specifics of your individual case.
