I get those pains occationally. Its like where you try to take a deep breath but it feels like your lung is caugh up on your rib or something. I can usually take about 1/3 of a breath before I get a super sharp pain that feels like its coming from me left rib just below my Chesticles.
Holy shit the exact same thing happened to me yesterday except I was jerkin off. I my heart felt like it was stinging and then I'd breath in and it would hurt, So I just lied in my bed breathing once every 30 seconds because it hurt so much, Then it just went away. I used to have a pain in my heart randomy but it was gone. Anf as Im typing right now my heart feels like it's tingly and weird lol.
i get some of those pains sometimes.. maybe it was a little anxiety attack? my friend had an anxiety attack before and her symptoms were pain in chest, weakness, ears popping, and tingling arms just like what you said
