I have no longer any panic attacks and the anxiety is much lower now. However, whenever I think about my condition or I get mad or in a bad humor my back feels like if there is something hot or cold in the spine area and there is still some trembling in the shoulder area. I have have not drink coffe in the last 6 months and I eliminated refined sugar from my diet, with the execption in which is included in the foods. I do exercise 3o min a day about 3-5 a week and do begining Yoga about 2-4 times a week. Is this a normal sensations when anxiety is vanishing? How long do they last?. has anybody experienced these sensations? They are not as bad but they are annoying from time to time. Any help would be appreciated
