posion ivy cures

thats what i’ve always done… I got poison ivy REALLY bad a few years ago to the point of which i couldnt move…

havent gotten it since and i’ve been in woods and everything fishing… :dunno:( even rubbing up against it)
is it possible to come immune to it?

I walked thru some wierd lookin plants a few weeks ago to get to a fishing spot and almost instantly both my legs felt like they were on fire… So much pain, burning so bad… and the pain only went away if i kept scratching it… legs got swollen and red, but after about a half hour everything was back to normal… I dunno wtf i walked thru…
