for the past week or so ive been having this feeling of bugs crawling on my skin so i hit where it feels like theres a bug but i look and theres nothing there. it feels like a bug biting me and it itches. it happens no matter where i am at home or work or outside in the car or even where im in the pool.. i dont think it fleas because i brought my dog to the vet and they checked her out and said she was clean. i dont know what is going on please help me
