I’m diagnosed with PTSD, psoriasis and bipolar disorder. For the past year I’ve been having what seems like a panic attack of my skin and I’m wondering if anyone else has them? All of the above have been treated well over the years but this symptom seems in its own league. When it happens its an intense itch all over my body that nothing eases. My pulse goes up and I want to scream. Usually an attack will last for a day but this last week it lasted for 3 days. Anyone else experiencing something like this?
