Hello and welcome to HCM, I read your query and understood your concern. The condition you are talking about is called ingrown hair / pseudofolliculitis. It is usually benign and harmful unless infected. Apply a salicylic acid/ lactic acid/ urea based lotion over the legs every night. These agent help in mild exfoliation and thus will reduce the recurrence of such condition in long term. Give yourself a bath with warm water and scrub your legs mildly. There is no immediate treatment to this except laser hair removal .But these methods will surely help in long term. Hop I helped
