Have Had Multiple Steroid Injections, Severe Pain. Injected For Sciatica. What Can Help?

I have had multiple steroid injections in my left and right bursa in the hips do to severe pain when I walk more than a 100 yards or so without stopping. Also have had injection for siatica. Since receiving the injections, I have started having extreme pain in the lower right leg, foot ankle, calf. sometimes in the left as well simultaneously. Its not just a cramp it is so painful I cannot stand or stretch to work it out. My husband tries massaging it but that doesnt help. The pain level is off the 0-10 scale...leaving me screaming and crying. I am at the point where I do not want to go to sleep for fear I will be awaken to another round of unbearable pain.
