I have found that sometimes when I have a reaction to a med & it seems to go away, it actually isn't all out of my system....so when I go back out into the sun, it triggers the reaction again. As time passes, if it isnt a reaction to something new, it will very slowly get out of your system & quit causing these reactions.

Hopefully if is isn't a reaction to something new, you system will clear the old just out soon.
