My symptoms are:
Heart beating quickly also known as "palpitations".
Shaking hands, arms, feet or entire body.
Shortness of breath:
Taking deep breaths do not feel "satisfying", or having to take deep breaths often.
Chest pain.
I don't feel like things are real. Feels like my head weighs a ton and almost feel dizzy. Also feel like I can't swallow and feat of fainting/dying I am so sick of it
For me, my heart starts racing, then I feel a chill, feel weak, sometimes get dizzy, headache, intense nervous feeling, clammy hands and like princess says you try to take a deep breath then your chest starts to feel heavy or pain then I start to panic about that on top of the initial freak out, I hate it but I refuse to take meds, youre not alone, hope this helps.
