I am having a sudden onset of little itchy bumps in the body. What to do?

Hello doctor,

So for the past couple of weeks, I have been very itchy and will break out in little bumps. I went to the doctor to find out if it was an allergic reaction or something else but they were not very helpful. They prescribed me Desonide for the breakouts. I have been using it but it has not helped with the itching. I also talked to a pharmacist and she asked if I had ever had experience with eczema I did when I was a baby, but I thought I had grown out of it. She recommended taking Claritin for the itching and using a moisturizing lotion and to continue using Desonide. I have been doing this for a couple of days and I am still itching like crazy. I do not know what else to do.
