My Dear Welcome to Healthcaremagic! I have assessed your description of the problem and think that this description matches with that of a Ring Worm infection. The following measures proved very helpful in clearing such lesions in my patients 1 Keep the area dry 2 Beginning with cream containing Miconazole and Clobetasone, switch over to plain Miconazole 3 anti allergic like Cetirizine control itching very well 4 Terbinafine is helpful in killing the fungus 5 taking acre of hygiene, ventilation of the area, and reducing perspiration are other great ways to check the problem 6 Reduce weight if you are obese and keep you sugar levels in normal range I am sure this helps you a lot. Best wishes
