Welcome and thanks for your question I am Dr. German I would be here to help you and give you all the assistance you need until you are satisfied, this is a basically a long term condition what you have. It is not dangerous but it is really uncomfortable . If the antiallergic medication is not working for you right now . There are other choices , many of them have proved to be really effective .
These therapies could be provided by a Dermatologist, so you will need to contact a Dermatologist in your area like :
1- A medication called Omalizumab , this medication is injected subcutaneously , it is basically an IgE monoclonal antibody , your condition is triggered by a Mastocyte cell reaction ( these cells release IgE and histamine ). Some patients experience complete relief with only one injection, others need multiple injections.
2- Phototherapy or light therapy is other good option , by itself or combined with Psoralen ( a medication taken by mouth ).
In the meantime , You could continue taking Cetirizine ( Zyrtec ) , you should also apply a Calamine lotion ( you could get this product over the counter ) or an hydrocortisone cream .
Avoid taking warm baths, do not use itchy clothing material ,drink a lot of water , do not scratch and use an hydrating cream like Shea Butter cream.
