"I have one leg shorter than the other"
I have a leg shorter than the other one

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?
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.
