Not sure if they are "bigger" per se, but they are softer and more elastic. The tops do not bind around your ankle, so no indents if your feet are swollen. You can also get them at Target.

This has been interesting about the sinus infections as I tend to get a couple a year. I am going to print off for the next time I get one and take to my doctor.

LizaJane and Silverlady, I hope you both feel better fast.
