I have had itchy bumps on my elbows for a year or so. I went to the dermatologist and they prescribed me fluocionide cream-it works for about 5 days then the bumps come back. Keep applying it for a couple weeks and it should work, as it did for me
Since it is located on your elbow I can tell you of a remeady that will control the itch. Put vinegar on the bumps with a q-tip. Dab it on several times, it will burn like crazy for a few minutes but then it will feel good for hours. After trying everything for a rash on my neck I finally found this to work.
