Leg cramps and pain in entire foot after BBL done 4/16/15.Ultrasound was done to prove it's not a clot. Ever heard of this b4?

Followup on prior questionregarding severe cramps from thigh to back of knee. I got answers from Drs to go to the ER but I went prior to the responses.I went to the ER 4/20 n ultrasound was done and they didn't see a clot.catscan was also done and negative as well I was admitted with a 7 hemoglobin and muscle breakdown that could affect kidney. I got 2 units of blood n 2 iron. There is less pain in thigh now but still tightness. Sometimes the foot feels like there's liquid but it's not swollen.
