Hi,
This could be due to an irritation or infection. Yeast infection may be asymptomatic and if symptoms are present, there is redness, itching, discharge and may be sore. Try to avoid self-medicating since this could lead to more harm than good. Have this evaluated by your doctor or urologist for proper diagnosis. Direct clinical examination is important and treatment usually depend on the underlying cause.
Take care and keep us posted.
Could I have a male yeast infection? With only a red rash that started out as 4 small red dots or spots? Treat with Monistat 7? Help please.
