<s>[INST] I have a very bright red rash around my crotch area.  It's not on my penis or testicles, just in the area surrounding them (upper, inner thigh mostly).  When this problem started, I also had very itchy bumps on both of my hands and had a fever...both of which have since gone away. [/INST] Hello,It may be due to fungal infection. For that you may apply ointment containing clotrimazole. For itching you can take tablet loratidine. Maintain proper hygiene.Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Shyam B. Kale, General & Family Physician </s>
