Does chronic hives signal possible future anaphylaxis reaction?

No. These are two separate entities. It is often difficult to identify the cause of chronic hives, and less often for anaphylaxis. But unlike some other allergic phenomena, there is no progression from hives to anaphylaxis. The best step you can take is to see an allergist to try to understand why you're having hives.
