I've been vomiting like crazy the past few weeks....I get spells and the doctor says IBS is blame but I think it might be panic related. I get obvious panic attacks when my mind is racing and thoughts spinning. I get the chest burning which seems to extend into the veins in my arms and my hands go numb along with the dizziness, shortness of breath and wobbly legs. My racing mind lends valuable insight which allows me to recognize it as a panic attack. But I'm now pretty certain I'm getting these attacks without the racing thoughts that I just assumed would HAVE to be present to be a panic attack. Why is my body panicking when I'm not thinking or ruminating on anything stressful? So bizarre! I don't tend to get the attacks while I'm actively dealing with the stress.....I seem to conduct myself well while dealing with stress and then crash afterwards and have the attacks after stuff calms down. It's all so weird. Your post was very helpful...thank you.
