Seems like medial tibial stress syndrome or shin splints.
Stop running for now, apply ice over the area, anti-inflammatory medications
Do exercises-hamstrings/quadriceps/calf stretching
Do all this for around 2 weeks- then start running on proper track(not hard surface), wear proper shoes,
calcium,
vitamin d supplements.
