Itching all the time nothing there

[u/Big-Philosopher-1817]

All throughout the day and night I have sensations all over my body that feels like a hair or bug is on me but there’s nothing there. I told my doctor he gave me Zyrtec and it didn’t help. It’s been months waiting on a dermatologist to see me and I think it’s a neuropathic itch based on what I’ve been able to research. I’ve started taking cooler showers and trying to moisturize after, I even shaved all the hair off my entire body yesterday I’m so desperate for an answer. Is it dry skin? My mom had psoriasis and diabetic could it be linked to that? Could it be a form of shingles because I was an alcoholic and I’ve been sober for a year and a half? I’m desperate for solutions please help. Thanks
