Yes, Yes, to just about everything you mentioned. I get creepy bug crawling sensations, itch/tickly skin, sometimes burning sensations, I think alot has to do with the muscular tension. I get the weird cold sensations, like someone is injecting ice cold water in my veins, and the worst is the tickly feelings that I get on my face. Have had these symptoms for 6 years. Had MRIs, bloodwork, everything comes out normal, except for a bulging disk in my neck. I just called my doc today, she had given me buspar, it drove me crazy, all the above symptoms were about a million times worse. She called in a prescription for Atarax, its a antihistamine/anxiety type med, I never heard of it before, but I guess its worth a try, I would give anything, except my son, for these feelings to go away forever!!! Your not alone. Its hard to believe its anxiety!!!
