Hi Tina,
Today is 8 weeks after surgery and my lymphatic system has not completely settled. Particularly on hot days I get very uncomfortable by mid afternoon. Best thing for me is to gently rub the side of the groin and then gently massage each breast for about 5 minutes. It sounds weird but I can feel trickling after a rub. Doesn't look to good in public! One breast is more uncomfortable than other. ( I had a bi lateral mastectomy and reconstruction and am basically very satisfied if uncomfy on and off)
Good luck. Time helps.
