Can my very severe seasonal allergies aggra ate the injury induced osteoarthritis in my ankle or am I imagining it. Had asthma attack first time today?

Not connected BUT. Pain is a subjective sensation as such anything can enhance its perception. Allergies have an immunologic and inflammatory. Each of these mechanisms could enhance the pain. How plausible each is is up to circumstances. You feel the pain enhances but i can't be certain why.
