Can cramping in my legs behind knee be dvt??

Not really: DVT usually causes edema and pain in the leg it would be unusual to get cramping . cramping usually muscular related but if u have doubts get a venous duplex scan that will answer ur question

Probably Not: Deep Vein Thrombosis (blood clot) is rare in adolescent males. You mention cramping in both legs so the likelihood is even less since DVTs are generally not symmetrical. Risk factors are smoking (use of birth control pills or injections in females), and long periods of sitting while not moving legs like on long car or plane rides or playing video games - but most teens do move legs when playing

Possibly: Cramping behind a knee can be a symptom of DVT. There are many possible causes of cramping behind the knee. Muscle strain, joint pain, trauma,sciatica, DVT ,even strenuous activity are just a few of the possible cause of cramping behind the knee. The likelihood of having a DVT increase if there are other risk factors such immobility, surgery, trauma, other illnesses.Seek medical care if concerned.

Yes possibly: A venous Doppler of the leg can diagnose DVT

Vein ultrasound.: The definitive test to show DVT behind the knee would be a venous duplex ultrasound. The accuracy of this test is over 95%.
