Hello I had been taking terbinafine 250 for a month for toe fungus. toes starting to look better BUT, now if I go outside in the COLD, or in the SUN shine, any part of my skin that is exposed turns red, swells and itches in TWO or THREE minutes of exposure. I will go back inside and it will take about an hour before my skin will stop itching and the swelling and redness will be all gone. I have stopped taken the lamisil about a week ago but, I m stil affected by the sun or cold air... Can anyone tell me what to do about this????
