<s>[INST] Hi, I have MS and am taking meds for it.  But for the past several months I have been in exterme pian when I  wake up each morning. I fell like a have a very HEAVY weight on my chest and arms.  I can barely get out of bed  i am very very weak all day long?? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. You are already suffering from Mitral stenosis (MS). This can cause congestive heart failure (CHF) and this can cause heaviness in chest, weakness etc. So better to consult cardiologist and get done 1. ECG 2. 2d echo 3. Stress test (trade mill test). You may need diuretics and other cardiac supportive Chat Doctor.  In severe cases of MS, surgical correction into the form of valve replacement is needed. So consult cardiologist and discuss all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
