My daughter 21 is experiencing an urticaria episode, Started Thursday so 48 hours now, she takes Fexofenodine but before we came away, currently in Spain, she took some amoxicillin for other health issue, apparently this causes sensitivity to sunlight which is hard to avoid in Spain, travelling home tomorrow but there's still no improvement, she has swollen hands and feet, her ears were swollen yday but that has gone down, some urticaria patches that were bad yday have gone, but more arrived in different areas, she's now got it on her forehead, under her hair, does she need Dr or can we wait to get home to UK tomorrow?
