I have recently(past 3months) been cleaning my body internally. 3 weeks ago I stopped using deodorant. I use an organic baking soda w/out aluminum with a bit of water. It works so much better for me. A few days ago I felt a bump that felt bruised under each armpit. I continued to use the baking soda as I feel it s not going to cause a dangerous reaction. Yesterday when I was drying off out of the shower I noticed a faint brown smear from each armpit. I noticed the same today and the bruised feeling and the bump is disappearing. I didn t see any scabbing. My question would be are my armpits excreting a substance that may have built up and deposited from using a deodorant with aluminum? (I used Dove deodorant in the past). Thank you
