Nothing can be said with surety without having a look at the lesions.
It would be best to consult your doctor about your symptoms if they do not resolve and get a proper clinical examination.
Keep the area clean and wear clothes washed in a few drops of chlorhexidine preferably and dried in the sun.
You could take oral antihistamine or antiallergic medications for the itching.
