Dear nrd1, thank you so much for mail. I cannot express my gratitude enough for such a thorough and kindly information.
You are right completely, also about migraine that I inherited from my mother. Even the jaw stress is there.
Also the factors you carefully enumerated are ALL present in my surroundings and acting to myself.
There is also high pollution in air, these years it has been the highest in the world as reported. People here having extreme problems breathing, sometimes we slept with masks on our face (without covid) and so on.
Thanks again for your letter, it really helps. All the best to yourself and your family.
