AIBU to want further investigation? For months now my chest has felt tight. Intermittent pain. Breathlessness etc. I haven't had covid as far as I know, haven't even had a cold. I'm only 30, but am in tears because I'm just so worried about my chest. I feel like I can't inhale properly. It's almost all the time now. They think it's my low iron levels. Iron levels were 6 (should be 30) they then went up to 10. I can't get them up as my periods are so heavy and all over the place. AIBU to want this looking in to further? I've never had anxiety over my health. Now it's all I think about.
