About to go on vacation early the next morning, I tried a recommended position with my legs up the wall and me lying on my back. It was to help blood flow for a long plane ride. The right thigh was quite a bit larger than the left. I didn't say anything to my husband as it would upset him a lot. Once we arrived at our destination I made an appt with the PA we often saw and the tests began. Cancer was the difficult possibility and I went home early.
