Lately i've started to feel this tightness in chest, above my heart, i get super aware of this feeling when it comes, which makes me anxious and very uncomfortable. My heart feels highly reactive, like it gets easily excited, shocked, scared. This feeling comes and goes. it's less profound in the mornings probably coz i take propranalol 20 mg, which im gonna ask my doc to prescribe me for afternoons and evenings as well now. But i m just wondering if anybody else can relate to this feeling? how did/do they deal/dealt with it?
