Had a pain injection in my lower right back June 2015 following on going back pain and struggling to walk without a limp resulting from car accident January 2014. The initial injection gave me 5 hours of relief was bliss until pain came back worse than ever. Having been moved to pain Clinic consultant decided a piriformis sciatic injection would be the cure. ..after waiting 6 months I had it done January 4th 2016 and I've never felt so much pain, loss of all feeling in my bad leg and pain I'm my lower right back. Has anyone had this reaction before?
