Hi within the last four days there are itchy red bumbs that have appeared on my stomach, they go all the way around it but mostly the middle and sides, at first they were small and itchy but now i see that they are more visible. I am afraid that this may be herpes, but recently i did change my detergent to gain could that be it. I took two benadryl last night hoping that would help. I had the herpes scare but my doctor said all test came back negative, but still a bit weary what could this be and what can i use to make it go away. Thanks in advance.
