Hello.
Thank you for asking at HCM.
I went through your history.
I would like to know your age, sex, any other diseases you have, any other medications you are taking, any other allergic disorders you have, etc. I would also like to know detailed description of your urticaria symptoms.
However, from your history, I would like to suggest you as follows:
1. Most important thing - allergy testing is not 100% to identify the cause, especially in cases of long-term urticaria like yours. So although you have been tested positive for a few food substances, personally I would suggest you to observe your food and correlate with urticaria.
If urticaria does not appear within 2-3 hours of taking a food item, even if it is tested positive, you may start eating it gradually. You may not be really allergic to that particular food item.
2. I would like to know whether you take any other medicines regularly. Particularly analgesics like ibuprofen,
diclofenac, etc can cause urticaria. In that case, please contact your physician who will suggest you alternative drugs.
3. Were I treating you, I would suggest you a short course of anti-parasitic treatment with nitazoxanide or
albendazole. Many times, intestinal parasites also can cause chronic urticaria.
4. Personally I would suggest you investigations like
complete blood count, ESR, CRP,
Thyroid function tests, Urine and stool routine & microscopic examination. These may give clue to cause of your urticaria symptoms.
5. For treatment, till the cause is found, I would suggest you to continue taking an antihistamine like
Hydroxyzine (Allegra, which you already have taken) or
Levocetirizine (Levorid, which you have already taken) or both on regular basis.
6. Please avoid activities causing
excessive sweating. Also, please avoid sudden changes in temperatures e.g., moving immediately from hot outsides to air-conditioned cold room inside.
7. Please avoid tight-fitting and woolen clothes. Loose, light-weight, cotton clothes will be best for you in my opinion.
Hydroxyzine causes more sedation. So I would prefer it to take it at night.
Hope above suggestions will help you.
Wish you the best of the health.
Should you have any other query, please feel free to ask at HCM.
Thank you & Regards.
