I m 20 days smoke free, and for the past 3 days I started experiencing chest tightness, mild difficuly breathing, dizziness, and intermittent skipping heart beats. I also have Type 1 diabetes and have had it for 20 years. I have experinece with anxiety and this is completley different. I saw a walk in clinic dr., and he said it is probably anxiety. I advised him this is very different. Ia m wondering if I should seek ER care
