Long driving trip. experienced pain behind left knee, where i have existing ver veins. 2nd day i had large bruise above knee. could it have been dvt?

DVT: Deep vein thrombosis is always a possibility with long trips. Usually dvts are associated with pain, swelling and redness. Also, watch if this is accompanied by sudden shortness of breath or dry cough. Occassionally dvts can throw a pulmonary clot or emboli (pe). To avoid this, be sure to make frequent stops in your travels, get out/up and walk around/stretch. I recommend you be seen.

Yes.: Mary, yes you could have a DVT after a long drive. If you are experiencing swelling and pain in your leg, you should see a doctor right away.

Yes: Could be clot in the superficial or deep veins. If still hurting , you need to be checked.
