Hello! Welcome and thank you for asking on HCM! I read your question carefully and understand your concern. Your symptoms seem to be related to anxiety. Nevertheless, it is necessary performing some tests to exclude other possible causes (like chronic anemia, thyroid dysfunction, adrenal gland dysfunction, etc.). I would recommend performing: - a resting ECG - a chest X ray study - blood lab tests (complete blood count, PCR, Sedimentation rate, thyroid hormone levels, cortisol plasma levels, fasting glucose, blood electrolytes, kidney and liver function tests). If all the above mentioned test result normal, the main cause of your symptoms would be just anxiety. A nerve conduction study would be necessary to examine for possible polyneuropathy. Hope to have been helpful! Greetings! Dr. Iliri
