With those symptoms and a recent surgery, a blood clot is on the lungs is the most likely event. You should be evaluated by a physician and I would recommend the emergency room so you can see a physician as soon as possible.
I hope this helps.
Thank you for your input. I went to the ER yesterday afternoon. After an EKG, blood work, an X-ray, and a CT scan I received a clean bill of health. They were glad I came in and said to get rest and hydrate. I am just glad I have insurance to cover most of the costs. Thank you again.
I should also mention that I am and non smoker and live a health and active life style with no previous medical conditions. I am 6'3" and weigh 166lbs. If that matters.
