Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. Stress and anxiety and itching rashes could be related. Stress Can Cause Hives. Mental stress increases the amount of corticosteroids released from your adrenal glands which are thought to alter the activity of your immune system. Hives develop after the release of histamine from immune cells in blood vessels near the skin causing swelling, heat, and itching. Reduce stress and live happy. Enjoy life. Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe some psychotherapy techniques which should help you cure your condition. Hope this answers your query. Available for further clarifications. Good luck.
