I've had an itchy rash that suddenly appeared one night its blistered into yellow blisters and is now turning a deeper red color have had this for 5 days now and the blisters are still raised and not really being relieved. Just wondering if anyone else has had anything like this or can advise on what it may be. Have posted before and had some say it may be Bullous Impetigo or a poison ivy rash, have been to the doctors and they had no idea what it was and to come back in 3 weeks if it isn't cleared but think that's too long to wait as I honestly have no idea where it came from as its only on my lower left leg. Just a little confused as to what it is and where it came from as I haven't used any new products or hurt my leg and have never had anything like this so it's very strange. Any help would be appreciated, thanks.
