Anxiety, new weird symptoms.

So, I started having bad health anxiety when I was 19. I'm now 22 and I'm pretty used to the usual symptoms I get but anytime a new supposed "anxiety" I always worry. Side note- I got my flu shot yesterday but since today I've been feeling pretty good all except that ive had a headache that I'm taking Amitriptyline for and also moments where I break out in a sweat and get nauseated and lightheaded. Could this just be anxiety? I check my BP and its fine too so im just worried

could easily be from anxiety. possibly the flu shot.if it continues or worsens or you get new symptoms , tell your doctor.
