I Went To The Er Thursday With Burning Sensation In

I went to the er Thursday with burning sensation in my veins. They ultrasounded the burning spots which showed no clots. I was sent home. The next day I passed a footlong tapeworm. The clinic prescribed me praziquantel. The pharmacy did not have it in stock at the time. I have since picked it up. Should I return to the er for further testing since they didn't know the burning veins were from tapeworms?
