<s>[INST]I just recieved a heart cath due to numbness in my arms all the way to my fingertips. Chest pain, facial cramping.... Everything checked out looking good. I have a cold feeling in my chest around my heart area but is more noticable when I inhale. Can you tell me what this may be?[/INST]Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that your symptoms could be related to anxiety. Anyway, considering the procedure that you have gone through, I would recommend performing further tests to exclude other possible causes that may mimic this clinical scenario: - complete blood count for anemia-thyroid hormone levels for thyroid gland dysfunction- blood electrolytes for possible imbalance- a cervical spine X-ray study for possible degeneration in this region or a bulging disc which may lead to irradiating numbness in the arms- inflammation tests (PCR, ESR) to investigate for inflammation. You should discuss with your doctor on the above tests. Hope to have been helpful! Wishing good health, </s>
