I tore my left knee on 4/16/13. at first i tried to let it heal on its own. then i started physicial therapy. i then started another session of physical therapy. with the second session, my knee was improving as I could start walking more than 10 minutes and was the proceeding to 20 minutes on the treadmill and then 20 on an imcubent running machine. however 2 weeks ago I started having problems breathing, short ness of breath in the evening. I assumed it was stress and anxiety from my job. however the shortness of breath has continuously become more frequent coming and going all night wherein i thought i was suffocating and it is now happening during the day. The PT checked my knee, leg, ankle areas for warmth, cold, pressure points and suspects a clot. Sunday I added vinegar to my diet. Monday and today, I included aspirin, raw garlic, raw ginger per what I read on the Internet of blood flow and clotting. Monday night I slept better. please help me with this diagnosis. thank you
