I had a lumpectomy and axilla node dissection (all lymph nodes under left arm) removed. A few months after I finished 40 radiation treatments I developed lymphedema in my left breast that was VERY painful. My oncologist originally thought I had developed an infection so he sent me to an infectious disease doctor. One look and he said you have lymphedema ! He referred me to a lymphedema clinic for manual massage that I did several times a week for approximately 6 weeks. The clinic was 35 miles away and a burden to go to but I did it. They recomended I get a lymphapress which I did to use at home. My insurance covered most of it. I uses as needed but it really helps to keep the swelling down in the arm and my chest area. I would look in to it. Has been very helpful to me. I am 6 1/2 years out now and have no issues. Use the pump only as need. The sleeve did not do much for me. Hope this is helpful.
