I HAVE A SHARP STABBING SEVERE CHEST PAIN THAT COMES AND GOES, IT LITERALLY MAKES ME STOP EVERYTHING IM DOING AND ITS VERY SCARY. ITS ON MY LEFT SIDE UPPER AREA. I HAD MULPITAL CLOTS IN MY LEFT LUNG AND I NOW TAKE 15 MG OF COUMADIN DAILY. I WENT TO SEE CARDIOLIGIST AND HE DID A D DIAMER TEST AND THE RESULTS WERE GOOD NO CLOTTING FIBERS, BUT THE PAIN IN MY CHEST IS STILL HERE. I WAS DIAGNOSED WITH PROTEIN S DEFIENCY WHEN THEY FOUND THE CLOTS 8 MONTHS AGO. I AM REALLY SCARED AND WHOULD APPRECIATE ANY ANSWERS. MY DEAREST RESPECT FOR THE DOCS HELPING PEOPLE WHO NEED THEM MAY GOD BLESS!

### output:

Thanks for your question on Chat Doctor. I can understand your concern. You are having protein S deficiency. It is hypercoagulable state. Intravascular clotting is common in this condition. So clotting and obstruction in the coronary arteries is also common. And this can cause sharp, stabbing, left sided chest pain. So better to get done 1. ECG 2. 2d echo 3. Stress test (trade mill test) 4. Coronary Angiography if required. If all these are normal then no need to worry much. Musculoskeletal pain can cause similar symptoms. So avoid movements causing pain. Avoid heavyweight lifting and strenuous exercise. Take painkiller and muscle relaxant Chat Doctor.  Apply warm water pad on affected areas. Don't worry, you will be alright, but first rule out heart diseases. Hope I have solved your query. Wish you good health. Thanks.
