Hi Cheryl,
Rash and itching in the armpits may be caused by a contact reaction to your deodorant/antiperspirant. Other possibilities include an infection of the hair follicles, sebaceous glands or skin under the arms. Sometimes the problem starts out as an allergic reaction but then turns into an infection because of the scratching and skin damage associated with inflammation.
Until you can be evaluated by a doctor you should avoid rubbing, spraying or applying the deodorant you previously used. Try to keep your armpits clean and dry (loose cotton top, air-conditioned indoor environment). The doctor will be able to tell you whether a cream should be applied. Other forms of treatment may be warranted based on more information about your history and your physical examination.
Best Wishes,
J. Thompson, MD.
Cheryl, I have been dealing with the itchy, dark underarms for years...and I recently, within the last year, have found the problem: itchy, dark underarms are related to insulin resistance. I obviously have been pre-diabetic for years and years...since childhood. But no one ever told me, even when I complained about the dark underarms that were driving me to distraction with intense itching! Last year, I ended up in the ER with terrible pain in my arms/hands. Diabetic neuropathy! Guess what? I didn't know I was diabetic!! Please go have that sugar checked! I have to wear braces on my arms and I am in constant pain. I wish someone would have cared enough to treat me years ago before this diabetes damaged my nerves. Good luck. Crystal
