Hello Mary! Welcome on HCM! Regarding your concern, I would like to explain that your current symptomatology (weakness and sweating) is nonspecific and may be related to several health disorders, including an ongoing inflammation/infection, a chronic disorders (cardiac, pulmonary, hormonal, metabolic, anemia, etc). Considering your recent health disorder, most likely causes could be the compromised overall pulmonary function, or right heart failure (not rarely found in important PE). Coming to this point, I recommend consulting with your attending physician on the opportunity of performing a careful physical exam and additional tests, including: - chest X ray study, - arterial blood gas analysis, - cardiac ultrasound, - anticoagulation level (INR), - complete blood count, - thyroid hormone levels, - liver and renal function tests - fasting blood glucose level At the end, you need to frequently monitor your BP and heart rate values and refer them when meeting your doctor in order to properly optimize your ongoing therapy. Hope you will find this answer helpful. Kind regards, Dr. Iliri
