I have had the same problem. It seems that I itch more when stressing and sometimes if I sweat. Also, lately in the evening. I don't know what to do. I went to the doctor and explained the symptoms, although at the time had no physical appearance of bumps and they gave me scabbies cream. I have sterlized everything in my home and vehicle and used the cream. It seems to work for a week or so and I start itching again. Any suggestions? This is driving me insane. Thanks.
