Last week i had three injections into my lower back. Since then i have had pains down my right leg. My leg is sore to touch and feels like there is shreds of glass in it. My GP thought i had a clot so took a blood test and sent me for an ultrasound and put me on 250mg of Lyrica per day. The tablets arn't helping and the pain seems to be getting worse. Has anyone else had this experience.
