Have high anxiety, went to er2x in dec and had negative chest xray and neg ddimers after chest pains, still have pains and now have cold symptoms, pe?

?PE: Often x-ray is normal in pe but hamptons hump or westermark sign are sometimes seen. D-dimer has a high sensitivity but low specificity meaning that if the test is negative, it is good for ruling out pe. If it is positive, it does not necessarily mean you have pe and further evaluation is recommended. If you look up well's criteria, you can calculate your pre-test probability.
