Health Anxiety and Real Symptoms?

I’ve had severe health anxiety for 2 weeks now, which was triggered by a panic attack after which I never felt the same. It caused me many physical symptoms where I feel like I’m sick. These symptoms are not going away even when I don't feel anxious. Do any of you have symptoms even without anxiety being present? Cognitive dysfunction, weakness, dizziness, fatigue… I mean I feel like I’m sick physically all the time, even when I don't feel anxious.
