Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. For breathlessness, your cardiac and respiratory function checked by EKG, pulmonary function test, chest x-ray, etc. If no cardiac or respiratory cause detected by above investigations than stress history should be taken to evaluate panic attack. Anxiety sometimes can lead to dyspnea by panic attack. So, if anxiety issues present psychiatrist can be consulted. Second, check your hemoglobin level to rule out anemia. If any family history of thrombosis present then kindly inform about that. According to the cause, specific treatment is prescribed Consult a physician for examination and discuss your case. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Parth Goswami
