See the site and the problem you have mentioned seems to be that of a fungal infection of the groin region.
You should not use soframycin
over the affected area.
Use an antifungal cream like canestan
or candid cream over the affected area twice a day.
Take oral fluconazole
150 mg tablet once a week. For the itching, you can take some antihistamines like levocetrizine tablet once a day.
Do not apply oil or any other cream over the affected area.
