Every night I wake up with a horrible burning itching sensation throughout my body, neck and face. It is only slightly noticeable externally but I feel this sensation as if it were under my skin. If I get out of bed and drink water and walk around and use a topical triamcinolon, the feeling does begin to abate and I can usually get back to sleep. I take lovaza, niaspan, a half tablet of alprazolam and a pain reliever, with sleep aid before I go to bed. What is going wrong with me?
