I get similar symptoms during intense attacks. It'll be hard to breath, chest will be tight, arms will tingle, etc. I'm glad to say I've gone nearly three months since such an attack! But yea, they're real scary to go through. I've been to the ER and had paramedics come out and check me out several times. That's actually what led me into researching anxiety, bc I tested clear for everything else.
Stay strong, and don't forget anxiety's ability to siimulate a pressing illness. It's just plain ol' anxiety, and it's not nearly as scary as it's symptoms may make you think. Hope today goes well for you Alesha :)
