Thanks so much for reaching out.
In many chronic hives cases, the triggers and causes are unknown. However, hives can be a symptom of numerous other conditions. Environmental factors, medications or auto-immune conditions (just to name a few) may all contribute to chronic hives. Hopefully others will chime in here with their personal experiences.
In the meantime, we always recommend bringing any concerns to your healthcare provider's attention.
