i am wearing compression stockings and taking lasix and potassium due to swelling in ankles. I am having heavy feeling in my left thigh. At times it feels like a ballon expanding inside. above knee feels tight first thing in morning and later in the day. I feel tenderness inside my thigh near the knee and at the groin in the morning. I feel lightheaded with standing for short periods of time. when sitting the back of my thigh hurts and I sometimes can feel a pulsing sensation.
