Hello,
Itching that is localized or occurs in certain parts of the body commonly is due to pruritis, allergy,
contact dermatitis or
psoriasis, etc. It looks like allergy due to sweat, pollen, dry skin, irritants (chemicals, metals, etc), scabies or body lice. You are suggested to take a warm bath regularly, keep your skin moisturised, keep humidifier. Reduce stress, avoid scratching. Maintain your hygiene.
You can apply
Soframycin cream in the areas affected. Cortico-steroid based creams and
ointments are effective. If it's scabies, you can apply Ascabiol lotion in the area affected. Keep it for half an hour and take a shower thereafter. It should go if its scabies. Repeat after 15 days. However you are suggested to get examined by a
dermatologist and get clinically examined. If sexually active you can get STD test done to stay on the safer side.
Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K, General & Family Physician
