Hi there.Thank you for your question.I will be helping you out with your concerns today.I am sorry to hear about your problem.
With the symptoms that you are having you would most likely require a short course of a steroid like prednisone for a week to two weeks.
This is much stronger and will help with your symptoms.
We also need to try and find out what caused the hives and for that you may require allergy testing.
Let me know if you have more questions.Please do submit a rating when you are done.Kindest regards
