Ok I am having this new symptom and wanted to know if anyone has had this or knows what to make of it. All this week on and off I have had this warm flush on my left front of thigh. Have you ever had a cat scan where they put that contrast in your iv and you get that warm flush down the middle of your body?. That is what keeps happening to my thigh over and over again. It does not matter if I am sitting or laying down. It keeps happening more often every day. Today it has happened to many times to count. I have a pinched nerve in my back but all my pain symptoms have always been in my right leg not my left. I don't know what to think. I do go back to my neurologist Friday and will ask, but just wanted to know if anyone els has had this feeling and if so any diagnosis on it?.
