Last night i started experiencing numbness and feels like my leg is really heavy or hard to use my leg normally. thought it was just me lying on my side too long. this morning i see just under my knee around the veins is a little swollen. ?

My concerns: You may have developed inflammation of the veins called thrombophlebitis. If this is the case, you need immediate attention to prevent embolic blood clots from migrating to the lung. An ultrasound study could objectify this. Other possibilities exist, but this is the most urgent area to be ruled out. Contact your doctor now, but an ER visit may be most prudent.

I suggest you go to the emergency room. There can be a clot in your leg and/or a neurological problem.

Agree with Dr. M & R. It would be prudent to rule out venous thrombosis. If you are overweight, it is imperative that you lose weight. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
