Hi I'm 17 and I have been having problems with my armpits for about three years now and I'm allergic to most ingredients in deodorants, so I started using toms naturals but they still don't help me.. . After I use deodorant a dqy or a couple hours later. . my under-arms start hurting, sometimes It gets sore and I can't put my arms down without feeling pain and sometimes I have lumps under my skin (under my arms) and sometimes it just turns red and burn, especially when in contact with a shirt that I'm wearing.. . can the lumps be a cancer ? (Says my grandmother) or is it just the deodorant ? What can I use instead ?
