Possibly: This is a problem that requires a face-to-face meeting with your doctor. In that meeting, your doctor will listen to you, perform a throrough examination and possibly order labs or other tests. Based on this information, he/she will be able to tell you what's wrong and what to do about it.

Yes: It is possible to have another clot you need to see a physician and probably be on medicine for awhile, some tests and be watchful for other problems. See a doctor.
