<s>[INST] I have some hard skin colored bumps the size of mosquito bites on my outer elbows. They itch sometimes. If scratched too hard they get a scab for a week or longer. No discharge. Sometimes I don t have any then I have several in the matter of a couple of days. Would you know what they might be? Thanks for your help! [/INST] Hi, thanks for sharing your health concerns with HCM!           If I were your treating Doctor for this case of itchy skin bumps, I would come up with three possibilities, these include: 1.     insect bites !2.     The second possibility is of fungal infection or viral rashes     3.     The last possibility is of some allergic skin condition I suggest you to go for routine blood tests and apply calamine lotion on the rashes and wait for 1/2 days! Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health. </s>
