Post mastectomy discomfit

Hi there @"Concerned daughter"...I had a bilateral mastectomy almost two years ago, with a full node clearance on the left and sentinal node on the right. My scar goes in a more or less straight line from armpit to armpit. I had a massive bleed after the surgery, which involved a return to theatre to open me up again and fing the bleeders. Eleven days in ICU followed and then another fortnight on the surgical ward. Long story...other medical conditions I already have contributed to this. The end result is a lot of thickened scar tissue and tightness. Feels like I'm wearing a really, really tight bra all the time. Also areas of numbness. I have two silicone prosthesis (Amoena), which I only wear when going out. Otherwise I go flat and free. I also find that the gentle, soft pressure they provide helps enormously with this sensation. I feel better with the bra and prosthesis than without. The reason I take them out at home is that they are very hot, and I sweat like crazy on my chest when wearing them.
