I keep getting random itchy bumps on elbows, side of knees, fingers occasionally, and on the inner part of my upper arm, not on my armpit but between them and my elbows. They appear  in clusters and are normally pale or light pink. I put hydrocortisone cream on them but they  constantly return. Could this be  the result of an environmental trigger or  possibly a disease?
Hi and thanks for using this panel for your health worries.I am sorry for what you are experiencing right now. The location of these itchy bumps, on exposed areas, make an environmental allergen very likely. It also responds to classical treatment but reappears later. This is probably due to re-exposure. The ideal thing would be for you to actively try to identify and eliminate the culprit allergen. If you cannot do this all by your own, then you may need to visit a specialist and get testing done.a disease could also be a possibility but its distribution makes this option less likely. I will go 95% for an environmental trigger and 5% for a disease. Hope this helps. Feel free to return to us. Wish you good health
