Hello sir and welcome.

Thank you for writing to us.

I have gone through your query with diligence and would like you to know that I am here to help. I would first like to put forward the option of attaching a picture of the affected region to our discussion for my viewing sir. This will give me an idea on the exact location, appearance, possibly even the exact cause/diagnosis and degree of seriousness. I shall completely understand if you are not comfortable with doing this. You should have an option to attach an image to our discussion (please attach a clear image) or you could email it to me at:

and do mention "ATTN: Dr. Shoaib Khan" in the address bar

In the meantime, I would like to put forward a few possibilities based on the information at hand for your reference sir:

+Fungal infection
+Bacterial infection
+Symptoms of a few sexually transmitted infections (e.g. syphilis, HIV)
+Chicken pox
+Dermatitis (seborrheic, contact or stasis)
+Heat rash
+Measles
+Eczema (different variants)
+Gangrene: due to poor circulation
+Pyoderma gangrenosum
+Psoriasis
and a few others.

Would you be so kind as to answer a few questions as well sir, it would greatly help:

+Your current sexual status (whether active or not)
+If at all you are sexually active, have you had any unsafe sexual contact (wherein there is a possibility of contracting STDs)?
+History of any chronic conditions (e.g. diabetes, cardiac conditions, hypertension, etc.)?
+History of fever or if it currently present?
+How would you rate your current personal hygiene on a scale of 0 to 5, 0 being poor and 5 being excellent?
