Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. About the ingredients of tooth paste, the same tooth paste has been used by so many people and it comes to market after intense tests. You don t have to worry about the allergic reactions. You can consult a physician if the symptoms persist. Stress is different. If you are worried about your stress level, take some days off and go for a vacation. You should not be stressed about the stress itself because it leads to anxiety. You can post a direct question to me in this website. Include every detail as much as you can. I shall prescribe some psychotherapy techniques to control your condition. I am sure that the techniques should be a success. Hope this answers your query. Available for further clarifications. Good luck.
