My daughter is 12 and she swells on different parts of her body. This has been going on and off since last yr. mostly her feet & hands. They swell up so tight it feels hard, it itches her a lot. It stays for a day or two then goes away for awhile. I have given her Benadryl but it does nothing.

What has her doctor said about this?

The doctor doesn't know what it is, she had her put ice on it at one time then another time she told my daughter to keep her feet elevated. The last time she was sent to a lymphodemia specialist, and they told her that she didn't have lymphodemia. We don't have any answers, benadryl doesn't seem to help any.
