I have lived with granuloma anulare for 41 years, I am 48. It completely disappeared during each of my three pregnancies which made me believe its cause to be related to a hormonal condition. I have been treated with creams, ointments, kenalog and light therapy ( along with an oral medication before light therapy). The longest lasting relief was the light therapy with second being Kenalog injection with topical ointments. I constantly hear that the cause is unknown and that you MAY OUTGROW IT, I don't think I will !!!!!!! Any new thoughts ?
