I have it as well. Slight swelling in left arm after mastectomy. I go to a lymphedema physical therapist. Amazing. Wear compression sleeves on flights.

I developed lymphedema in my chest, arm, and hand on the left side a few months after I had lymph node removal and radiation treatment. Mine is not painful. I can just tell that it’s swollen when compared to the right. I go to a lymphedema specialist once a month now.I use compression garments day and night and I have a pump that massages my chest, arm and hand that I use every night before bed. Our goal is to keep the swelling from increasing. I hope all goes well for you.

It's a condition often caused by radiation or surgery. Lymph fluids accumulate in places like the chest, arms, legs or stomach because the lympjapgatic system is damaged or blocked.. Let your doctor know right away if you are having fluid accumulation so you can get the proper treatment. Good luck to you! Please stay in touch. Prayers, hugs, love!!
