Hello! I am 34, male, and had anxiety disorder for many years. Recently i started to had these attacks and i dont know if they are related to a heart issue, some lack of minerals, psychology related or all of them. It happened yesterday and today as well. First i was in the subway standing and i slowly start to feel a little pressure in my chest which slowly starts to become like a numbness and is expanding across my chest and belly.. I feel i have to breath faster but it still feels like not enough. It doesn`t feel like pain. It also happened when i was just sitting somewhere at Mc Donalds and eating. The thing is that it happends when i stand still somewhere. The soon i started to walk, i get better and then it dissapears. I even tried to run after and didn`t had any issues. I do feel the urge to sigh for a couple of days though. I think during these attacks i have low blood pressure or low heart beat.
I want to add that i have been very stressed lately and also been through a diet and lost some weight. Do you think that because i feel better when i walk is a sign that is not a serious heart issue? Maybe i need more minerals or i should just do a blood test... Thanks !
