Why is my testicle skin peeling and itchy?

Your scalp problem could be a medical issue that requires medical treatment. I recommend you should pay a visit to a dermatologist, who is a skin expert. They can detect the condition and recommend the medications or treatment option that should be taken. Avoid using any harsh chemicals on your scalp until you have been to a doctor.
 

You may have a fungus infection in your groin. It may result in scratching and irritation of the affected areas. I suggest you go to a dermatologist who can diagnose and cure your disease.
 

Yes, definitely! Starting iron supplementation can help improve your skin color. Symptoms of low iron, like pallor and fatigue, can show up in your body. Most iron deficiency is due to not getting enough iron in your diet. A balanced diet should include iron-rich foods like spinach and meat. Seek advice from a healthcare professional for suitable recommendations.

I suggest that you visit a dermatologist and have them check out the mole on your nose. They can tell whether the mole is a benign or malignant one. However, based on the diagnosis, surgical removal or any other alternative mode of treatment may be recommended by a dermatologist. I suggest consulting a dermatologist near you for further advice. The treatment cost is determined by the recommendations and location of a particular clinic.

Without a proper evaluation and diagnosis, I can't say. But normally, suggested treatments for perical pigmentation include topical medications and laser treatments and I do not recommend flutivate cream for pigmentation. However, based on your individual condition, the doctor will recommend the best treatment for you.
