The skin area, under my bra, under both arms and across my back have felt sunburned for about 5 days, but nothing was visible or rashy. Yesterday morning a red rash the on an area the size of an eggs appeared. There were also several smaller rashy areas near by. This evening the rash is larger and has spread onto the side of one breast. There are now a few small red blisters or bumps on the welts. I am a 62 years old female. I care for my 18 month old granddaughter during the week and I am now worried she might catch something from me.
