So last night I was a bit itchy near my left underarm, so I scratched it. I have been using the same deodorant for awhile now, and it never had a negative effect before. I remember having a similar reaction many years ago with another deodorant (Arm and Hammer "Sport") I used for over 3 years, but I had to switch deodorants after I moved countries since it wasn't available to me anymore. Anyway, after scratching near my itchy left underarm, I develop an itch elsewhere. Eventually, the itch moved to my neck, close to my left bicep, my inner and outer thighs, my groin, ass, my calf muscles, right bicep, my back, random parts of my chest, and even my right underarm area. Needless to say, i had a lot of trouble falling asleep last night. I took 2 showers and changed t-shirts after hell broke loose. I mean, after looking at the areas just listed (ie: groin, ass, neck), these are places I likely scratched after touching my left underarm! So am I allergic to my deodorant or something? Is that possible seeing as how I use that stuff every day with no effect before? Could it be cause by something else? Maybe I believe it has to do with the scratching my left pit when in fact it's not related to the scratching whatsoever. I don't know if this is considered a "rash" or "hives," but there are red itchy areas all over my left shin right now, and it's really really itchy. The area is not just red. Entire areas are slightly "raised" relative to the rest of my skin.
