I started getting <span style = 'background-color: #dae8f4'>boil</span>s
the inner side of my lips after I started taking the birth con
trol pill. After a while of being on
it, they seemed to go away (with the occasion
e or two right before my period). However, they still have a tendency to break out if I swim a lot. Ther
efore I assume the cause is mainly hormon
al and then aggravated by chlorine/environ
ment. I found the best way to limit my outbreaks is to use a washcloth and carefully clean around the area.
