When I feel stress or think negative thoughts, then immediately i feel tightness sensation in whole head area, hands become tight numb, toes become numb. Weird sensation of tightness, pain like someone is pulling my nerves. My blood pressure is normal, but when I fear of future or regret about past career opportunities i missed or any other good things i missed in life....like never socialised with people much in youth... i suddenly I feel this...earlier I never faced...but now on even slightest anxiety or worry, numbess happens..since few months constantly im facing... can this be ever cured of is it permanent??
