Suffering from poison ivy (5)
I believe the answer is:
itchy
'suffering from poison ivy' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for itchy that I've seen before include "Affected by desire" , "Like the feet of the restless" , "Causing irritation to skin" , "Requiring a scratch" , "Bothersome" .)
