Rash involving both armpits starting this morning upon waking, 12 hours later this evening starting inguinal area. Itchy, burning, some changes to the skin including thickening/swelling. Rash is extensive in armpit area but the lymph nodes are not swollen. I have not changed anything (deodorant, laundry detergent, perfume, nothing), was not in contact with any foreign substances. 32 years, F, gravida 1 para 1. Have tried Benadryl - no change whatsoever. Hydrocortisone cream - no change whatsoever although the itch subsides for about 15-20 minutes. Did feel somewhat strange last night, mild flu-like symptoms lasting about 2 hours that spontaneously resolved before I went to bed.
