<s>[INST] Hi doctor, I have got cracks on penis cap skin, and it is tight. I am not able to retract it. Light irritation is there and is uncomfortable. [/INST] Hi. I have seen your query and examined your given picture (attachment removed to protect patient identity). It seems you have developed balanitis xerotica obliterans. Do you have diabetes? It is more common in diabetics. Clean the penile area with normal tap water, try to pull foreskin gradually while taking bath. Use Clotrimazole plus Fusidic acid cream local application twice daily and take tablet Fluconazole 150 mg once a week for four weeks after consulting your GP or nearby dermatologist. </s>
