So as of about a week ago i started getting pain in my lower leg. it was a weird kind of pain it felt like it was like deep inside of my leg and it would come and go for about 5 days. At that point i had already started to believe i had a blood clot in my leg but yesterday it went away and i forgot it. then today i started to get a cough that ive had for about an hour now and i cant stop thinking about it and googling symptoms. Is there a possibility i could be having a pulmonary embolism ??
