Hello, Thank you for asking at HCM. I went through your history and would like to make suggestions for you as follows: 1. There are many causes for hives. So more detailed history and description is required to give more specific suggestions. 2. Parasitic infections, viral infections, bacterial infections can cause hives. 3. Some conditions/normal activities like sunlight exposure, cold/warm water exposure, exercise, sweating, etc can also cause hives. 4. Food allergies and food intolerance can cause hives. 5. Hives can also occur due to adverse reactions to preservatives/coloring agents/flavoring agents etc in packed foods/outside foods, some drugs like NSAIDs (used as pain killers), some antibiotics, etc. 6. In some patients, hives can be difficult to treat, like those with chronic conditions, autoimmune urticaria, etc. 7. Stress can aggravate some hives. 8. For treatment viewpoint, I would suggest you to take antihistamine like levocetirizine or cetirizine or fexofenadine for symptom relief. 9. I usually suggest complete blood counts, ESR, CRP, thyroid functions, serum total IgE, urine and stool examination to investigate patients with repeated hives as first line investigations. If these investigations do not reveal any abnormality, more detailed investigations might have to be done. 10. I usually also suggest my such patients a good multivitamin-multivitamin containing vitamin A, D, E, zinc, selenium, essential fatty acids, for 2-3 months which improves skin and immunity. 11. I would also suggest you to apply moisturizing lotion/cream regularly, especially if you have dry skin. 12. Unfortunately, despite lot of investigations, around 25-30% hives remain undiagnosed. Hope above suggestions and information will be helpful to you. Should you have any further query, please feel free to ask at HCM. Wish you the best of the health ahead. Thank you & Regards.
