I have been a hair stylist for 10yrs and about 1yr ago i noticed a chain of lymphnodes showing in my armpit,they dont hurt or bother me just want to know why i have them all the sudden. I have been to a few dr and they dont think i should worry,but its not good enough for me because i need to what they are from. Hair chemicals i know can be bad when your around them all day every day,and they seem to be bothering me more than they used to. I get headaches about half way through the day and they burn my throat!! do u think my body is trying to tell me something???
