How likely is it to have a blood clot in both legs? what does the pain feel like? my legs hurt

Unlikely: When referring to blood clots in the deep venous system. it is uncommon to have them at all unless there has been a recent major operation or trauma. Leg pain can have many causes, and requires a more complete evaluation. You should see your primary care provider to get this - the timing of which should be based on the severity and duration of symptoms. Hope this helps!
