Had two ultrasounds on my left leg to check for blood clots fount no clots still have pain in leg on calf and lower leg is that pretty good for both to come back with no clots fount?

Sure it is good. It is good that you do not have blood clots such as dvt's in your legs. If still with pain, keep getting evaluated for the pain and hopefully a diagnosis will be forthcoming, so the proper treatment can start. Best wishes.
Need to look for. Other cause of the pain, muscular, nerve pain.......Work with your doctor to look for other causes of the pain based on your symptoms and exam. Good luck.
What about chemical. Sometimes the pain is neuro-muscular. Have you had your electrolytes checked and what about your blood circulation .
