I'm having extreme pain in my left leg and my toes are tingling . It's almost like a tooth ache but in my leg. It's right from my hip all the way down and also feels like shin splints are happening. Sort of also feels like a lot of pressure is going on and like there might be some kind of blockage or like my artery is going to burst. I haven't done anything to it for this to feel like this. The only thing I can think of is I had an intravenous contrast injection yesterday and a CT scan. I was very sick from the contrast injection and now my leg is in so much pain I can't even sleep. Pain meds won't take the edge off either. Is there anything I can do to help it ? Heat doesn't work, elevating it doesn't work, pain medication doesn't work. I need to sleep but can't! Someone help!
