Dysesthesia, or knowing the words

I went to the dermatologist, who called the flaking on my eyes Eczema.  He called the lesions on my genitals something else (I forget).  He gave me a cream for both.  And told me to take Zyrtec for my itching.

And he gave me a name for my pins and needles: Dysesthesia.  He said that he has seen it in IFN cases. And he also mentioned some drug that may be useful in treating it.  But then backed off, and said I should ask my Oncologist, because it was out of his purview.  I forgot the name of the drug.

It feels really good to have a name for this mysterious side effect.  And a wikipedia page.  That helps too.
