I was playing baseball and was running when i got a pain in my right quadricep.a day after pain still.could be dvt or something else?no redness/swell.

Pain: Sounds like you pulled the quad it really doesn't sound like dvt, your doctor can check it and advise you.

Less likely : More likely a strain since you are active. The veins are generally behind the knee.

Leg pain: it is more likely that the source of the discomfort is due to a muscle strain, as the discomfort began while running. However, if you are concerned with regards to a deep vein thrombosis, then a venous Doppler sonogram would be the definitive test to determine that issue.
