I have suffered from red sore lips that go really dry and scaly then peel then it starts all over again, Ive also had bouts of mouth ulcers.This has went on around 4 months and is really getting me down ! my gp has tried antibiotics, steriod creams and antihistimes, but nothing seems to work. They have now suggested it could be caused by medication im taking (citolpram) which could cause photosensitivity. Id be gratefull if any could have anything that may help me sort this !
