dermatological disorders
"I have been highly prone to sunburning my lips, although my skin rarely burns.  At times my chapstick with spf wears off before I can reapply so I treat the resulting swelling, burning, and sometimes blisters with pramosone.  It quickly relieves the pain, burning, and helps heal my lips more quickly than any medicated chapstick or ointment.  Pramosone is a savior for my sunburn."
