I am  suffering from skin rashes and hives from past one year . Multiple Dermatologists said that it is because of urticaria and gave antihistamines. But these antihistamines relieved me only when I took tablet else again randomly these hives occur again and again. Recently in full body check up hepatitis B came reactive with patient value 11.14 . Are these rashes because of this virus  How severe is this and can it be cured . Do I need to take hepatitis B vaccine now or medication remove this from my body . Thanks in advance
