Hey.. I have been experiencing hives with itching since 10 days.. I had a cold and took augmentin 625mg for 5 days and from the next day, started getting the rashes (have tamen the same med. before but got no reaction then). The rashes are symmetrical, generally occur on my back, arms and neck, sometimes stomach.. They are very itchy.. Had taken levocetrizine on two days which helped in subsiding the rashes.. The rashes come and go in 15 -20 mins but redness persists for around half an hour.. They generally appear late in night or in early morning (when I am up at that time) they are subsiding now and occur less frequently, but surely in early morning.. What can be the cause?! Do I need to get some tests done?! Plz help. Thanks.
