<s>[INST] Hi doc I noticed a pimple on my foreskin a week or 10days ago. I took it lightly as i thought it to be normal infection due to moister in that area. But suddenly it started severe itching at tip of my foreskin. And now it has increased to 4. I am 27 n sexualy very active. Please advise what is the reason behind. I am very worried... [/INST] Thanks for asking in healthcaremagic forum  By your description it is possible that it is of infective origin. So, please visit a dermatologist for physical examination and further management.  If you can upload the pic of the lesion, it would have helped us to diagnose better.  All the best. </s>
