If this is happening to any of you, chances are decent that a chiropractic adjustment will solve this issue. When the pelvic area becomes tweaked, one leg will be drawn up and the other pushed down.

why not רגל אחד?

[Hava_Dorit]

Because רגל is irregular when it comes to forms. It's feminine with a masculine plural (רגליים). So is יד, ידיים. Feet and hands are both like that in Hebrew.

I hope this helps.
