Dealing with Sciatica pain

Am dealing with pain on my left side radiating down my leg with numbness and tingling, diagnosed as sciatica. MRI showed two bulging discs and spinal stenosis. Ironically, I question whether the sciatica is from the above, but may involve my piriformis muscle. I had this problem in 2009 and my neurologist injected a steroid into the prirformis and I had relief for all of this time. After taking steroids with no relief I asked for a shot in the piriformis (rather than an epidural) and this has helped a little. Am due for another shot soon. I am now also having severe muscle cramping in my groin and thigh upon standing and walking, which is very painful. Would appreciate anyone's input. I am going to look into PT and ART (active release technique). Thanks for your input.
