Hi Doc I had about 10 small freezing injections into my arthritic,bony growth laden lumbar spine and SI joints yesterday,in search of a place soft enough to inject 3 main Lidocaine steroid epidural injections.I felt quite relaxed after the treatment,and better since. I had blood in my stool this morning,medium red colour,with loosish bowel movement-light brown colour. Was the blood a possible result,of my epidural session yesterday ?
