Respected Ma'm
1. The pain in pulmonary embolism usually occurs when the smaller emboli (blood clot) block smaller and peripheral blood vessels leading to the death of lung tissue they are supplying. This leads to seepage of blood into the potential space around the lungs (pleural sapce) covered by a thin sac called pleura on both sides. The irritation of outer part of this sac by blood leads to pain. At times the inflammation following infarction extends ot tihs outer sac. Usually this happens 3-7 days after an episode of pulmonary embolism. The smaller emboli do exist with larger emboli at times. The pain persisting even after one month of primary episode may be due to recurrent embolism or due to presence of inflammation/ blood / fluid in pleural sac. There can be some unrelated cause of pain too. this may be related to lungs or structures outside lungs like muscle, bone , soft tissue etc. The characteristic of pain of pleural origin is that it increases with deep breath and cough and patient winces in pain at height of inspiration.
2. The pulmonary infarction syndrome may take ~3 weeks to resolve, if no new episode occurs. However The exact duration also depend upon the cause of pain in a particular case.
I would recommend you to get your self examined by your primary treating physician to ascertain the exact origin of pain and if he / she is not available, have an appointment with your GP.
Hope this helps. Feel free to discuss further.

Could you tell me what a ct angiography is and why it's carcinogenic?

Detailed Answer:
Respected Ma'm
1. A CT angiogram is a procedure where a XXXXXXX is used to opacify or visualize the pulmonary arterial tree (the blood vessels supplying the lungs) and pictures are taken by a CT scan machine. The same procedure may also be used to visualize coronary arteries (vessels of heart) or any other arterial system in body.The XXXXXXX is given through a catheter (or cannula) in your vein. This can show up to 6th generation (or 6th division) of main pulmonary artery. If there is any filling defect in the tree is taken to be a mass lesion or thrombus (blood clot). This is the procedure of choice to confirm or rule out pulmonary embolism in suggestive circumstances.
2. The CT scan carries low carcinogenicity or cancer causing potential with single exposure.The radiation dose is 2-10 milliSV depending upon the scan. This is considered as low risk for cancer. A single exposure less than 30 milliSV or an exposure of 100 milliSV over a short period of time is considered as low risk by some authorities. The CT scan is just like an exposure to large number of x-rays and x-rays are carcinogenic. They have the ability to damage DNA or genetic material in the cells which may cause cancer.
Hope this provides some insight.
