Rash and itching due to binder, but can't go without it due to severe swelling. Suggestions?

Hello, often a barrier (like the cotton shirt you have tried) will help a rash like this resolve. If not, perhaps there is another type of binder or compression garment that could be worn, as well as medications and/or creams to help resolve the rash and itching.  I would suggest discussing the issue with your PS because they will be able to make specific recommendations.

 Thank you very much for sharing your concerns with us.To reduce the swelling I recommend you perform daily lymphatic drainage massage therapy over the abdomen and wear a postoperative girdle from thigh to the breasts. If your binder gives you rash i recommend you to talk with your surgeon to search for another compression garment.Respectfully, Dr. Emmanuel Mallol Cotes.-

If you are still experiencing a lot of swelling I would suggest you keep wearing a binder. I would agree that spanx do not provide enough of the stretch support that you are needing. If you are finding that a shirt underneath the binder is making no difference you may want to do some research into the different waist trainers of fabric corsets that exist. Hopefully your can find something with enough support and a fabric that does not cause you irritation. Best of luck.
