Not me, but I suspect that pulmozyme gives you sabaceous cysts. I never had these problems before doing the stuff, but for a long time now i'll get a zit like on my back, and if I dont catch it right away it will turn purple with thick blood, and if I still dont squeeze that blood out (it hurts a LOT, cause its forming a pocket cyst in there with blood) and it sprays everywhere, it will turn into a solid cyst. I had one removed off my back a long time ago which hurt like crazy. I had an MRI done a long time ago where one doc said he saw a cyst on my brain stem. It seemed to have turned into nothing.
