I have a lump under my left arm down from my arm pit about 3 inches. I can feel the pain down. I to my elbow. Sometimes worse than others. I have a great deal o skin under my arm from being very over weight 15 years ago. The lump is hard to find and about the size of a nickel. The pain reaches my wrist sometimes and the thumb and next two fingers go numb on my left hand. I had a small mole like growth on my left nipple and had a mammogram that turned out fine. I have an appointment with a breast specialist in August. I am at a loss as who to see and what to tell them. I am 75 years old. Thank you for taking the time to look at m question. I don t think I am a hypochondriac but I am beginning to wonder. Thank you for taking the time to read my message. Nancy
Welcome to ChatDoctorYou may be having melanoma over nipple which has spread to axillary lymph node giving lumpy feeling in armpit. Mammography may not pick up nipple growth and best test to diagnose the disease is biopsy of growth. You should see a surgeon for confirmation. Armpit lump also needs biopsy. Regards.
